Chapter Summary: “Yukinoshita’s Correction Method”

Key Plot Points and Events

• Yukino Yukinoshita criticizes Dong Yunshan’s reluctance to follow her detailed early-education plan for his six-month-old sister, Dong Yunxi. She argues that early education should consist of focused companionship, games, and meaningful interaction rather than passive entertainment or solitary play.
• Dong Yunshan receives a commission concerning school bullying in Inage. He contacts his associates, instructing them to investigate the situation and stop the bullying without using violence. He emphasizes obeying the law and publicly exposing the bully through a nonviolent nickname-based confrontation.
• Another call comes from a friend who previously helped Dong Yunshan locate Yuigahama’s childhood friend, Little Flower. The friend has moved to Tokyo and wants to meet. Since Dong Yunshan must care for Xixi, Yukino volunteers to look after the baby so he can go.
• Yukino frames this decision as repayment for Dong Yunshan’s assistance to Yui Yuigahama and as part of her responsibility as Service Club president. Dong Yunshan recognizes that her willingness to help shows that his efforts to make her more considerate and socially engaged are beginning to work.
• After Dong Yunshan leaves, Xixi wakes from her nap and happily interacts with Yukino at first. She points around the apartment, seemingly searching for Dong Yunshan.
• Once she realizes he is gone, Xixi begins crying intensely. Yukino is overwhelmed and discovers that caring for a baby is much more difficult than her carefully designed plan suggested.
• Yukino successfully distracts Xixi with a spinning toy, noticing that the baby shares Dong Yunshan’s apparent fondness for spinning objects. She then feeds Xixi and begins turning playtime into simple educational exercises.
• Yukino teaches Xixi object permanence by hiding toys in a box and under a towel. Xixi gradually learns to uncover them and receives enthusiastic praise.
• Yukino next tries to teach Xixi how to pull a toy closer using a ribbon. Despite several demonstrations, Xixi simply hands the ribbon back. Yukino eventually realizes that Xixi has been focusing only on the toy and has not been watching the ribbon at all.

Character Developments

• Yukino Yukinoshita: She remains strict, logical, and highly organized, but her confidence is challenged by the realities of childcare. Her theoretical plan initially fails when Xixi cries, forcing her to improvise. She adapts by observing the baby’s interests and using play to calm and teach her. Her decision to babysit also shows growing empathy, responsibility, and willingness to help others.
• Dong Yunshan: He appears protective and responsible, particularly in his handling of the bullying commission. Although he jokes about his physical strength, he insists that his associates investigate carefully and avoid violence. He also trusts Yukino enough to leave Xixi with her, though he correctly suspects that her plan is overly ambitious.
• Dong Yunxi: Xixi is shown as affectionate, observant, and strongly attached to Dong Yunshan. She communicates through pointing, gestures, and cries, quickly becomes absorbed in spinning toys, and begins learning basic concepts such as hidden objects. Her behavior also exposes the gap between Yukino’s expectations and an infant’s actual abilities.
• Yui Yuigahama: Though absent, Yuigahama motivates Yukino’s decision to help. Yukino’s awkward explanation reveals that she still struggles to openly describe friendship and emotional obligations.

Significant Themes

• Theory versus practical experience: Yukino’s carefully structured educational plan collapses when faced with a distressed infant, demonstrating that real caregiving requires flexibility rather than rigid preparation.

• Xixi’s attachment to Dong Yunshan becomes clear when she searches the apartment for him and cries after realizing he is gone.
• Yukino gradually develops a playful, nurturing interaction with Xixi, using spinning toys, feeding, praise, and hiding games to calm and teach her.

Chapter Summary: “Yukinoshita’s Correction Method” / “This Really Is Correction” / “Being Full of Yourself”

Key Plot Points and Events

• Baby Xixi appears to say “mama,” briefly making everyone think she has spoken her first word. Yukino explains that Xixi was trying to imitate the “meow meow” sound she had taught her, and that the similarity to “mama” was accidental.
• Xixi deliberately keeps making the sound because she recognizes that it makes everyone happy. After feeding her, Yukino performs gas-relief exercises, and Dong Yunshan successfully settles the baby to sleep using a cushion and blanket to recreate the feeling of being held.
• Yukino, Dong Yunshan, Yui Yuigahama, and Komachi Hikigaya prepare lunch. Yukino assigns Dong Yunshan household chores, while the girls help in the kitchen. Yui is removed from the kitchen after Yukino reveals that she tried to wash meat with dish soap.
• The chapter explains why Yukino continues helping care for Xixi even though Dong Yunshan never used his second “command” to make her do so. Yukino considers her assistance part of her effort to “correct” Dong Yunshan.
• Yukino and Komachi discuss Dong Yunshan’s emotional condition. He acts like an exceptionally capable adult despite being a high school student, maintaining emotional distance from others and treating situations as though he is observing them from outside.
• Yukino identifies this behavior as potentially resembling dissociation and believes it could become dangerous if left unaddressed. Her duels and commands have been intended to revive his competitiveness and strengthen his self-awareness.
• Dong Yunshan later explains that he is also trying to correct Yukino—not her social behavior, but her excessive perfectionism.

Character Developments

• Dong Yunshan: At home, he is obedient, competent, and comfortable with childcare and domestic tasks, contrasting with his more confrontational school persona. He recognizes that Yukino is helping Xixi rather than merely obeying him, and he understands that her actions are part of her attempt to help him reconnect with his emotions. He also becomes more perceptive about Yukino’s psychological weaknesses.
• Yukino Yukinoshita: She demonstrates strong maternal and domestic competence, coordinating naturally with Dong Yunshan in caring for Xixi. Her “correction” method is revealed to be deliberate and psychologically motivated: she uses competition and commands to draw Dong Yunshan out of his detached adult persona. At the same time, she is shown to be excessively perfectionistic and unable to forgive herself for mistakes.
• Yui Yuigahama: Yui notices the difference between Dong Yunshan’s public and private behavior and begins to understand the seriousness behind his actions. She also gains a more nuanced view of Yukino, realizing that traits she admires may place enormous pressure on her.
• Komachi Hikigaya: Komachi perceptively identifies Dong Yunshan’s forced maturity and helps articulate the emotional exhaustion underlying it. She also assists Yukino effectively in the kitchen, showing her practical competence and sensitivity to Yukino’s habits.
• Baby Xixi: Xixi shows growing awareness of facial expressions and emotional responses, intentionally repeating sounds that make others happy.

Significant Themes

• Correction and mutual healing: Yukino and Dong Yunshan are both trying to “correct” one another. Their relationship is not one-sided; each recognizes the other’s emotional imbalance and attempts to help.
• The burden of forced maturity: Dong Yunshan has adopted standards suited to an ideal adult, causing him to distance himself from ordinary teenage experiences and emotions.
• Perfectionism and self-punishment: Yukino’s determination to do everything correctly becomes unhealthy because she interprets failures as personal shortcomings, refuses to compromise, and cannot forgive herself.
• Emotional connection through responsibility: Caring for Xixi creates an environment where the characters cooperate naturally and reveal sides of themselves that are less visible at school.
• The danger of emotional detachment: The discussion of dissociation emphasizes that appearing calm, reliable, and mature can conceal serious psychological distress.

Character Interactions

• Dong Yunshan and Yukino work together seamlessly while caring for Xixi, communicating through routine and mutual understanding rather than words.
• Yukino teasingly assigns Dong Yunshan chores and maintains control of the household, while he accepts her instructions without the resistance he usually shows at school.
• Yui and Komachi observe the pair’s domestic coordination and begin to understand the deeper psychological motives behind it.
• Yukino explains Dong Yunshan’s problems to Komachi, while Dong Yunshan separately explains Yukino’s perfectionism to Yui, creating a parallel structure in which both characters are analyzed and “corrected” by the other.
• Yui initially defends Yukino’s personality as admirable self-assurance, but Dong Yunshan helps her see how that same independence may have developed into damaging perfectionism.

Summary

Dong Yunshan explains to Yui that his approach to Yukino’s perfectionism is deliberately gradual. Because Yukino tends to shoulder excessive responsibility and pursue flawless results, especially in situations where there are no clear standards—such as raising a child—he follows her plans as closely as possible and allows her to confront imperfect outcomes. Deliberately undermining her would only increase her distrust and reinforce her belief that she must handle everything alone. Yunshan admits that the correction cannot be completed in one week; he is helping because he once encountered someone he could not assist and now refuses to ignore a problem he has the ability to address.
Yukino agrees with this philosophy, emphasizing that problems should be addressed while action is still possible. Komachi repeats Yukino’s principle that failing to do what can be done now may eliminate future opportunities to help.
After spending time caring for baby Xixi, Yui realizes that Yunshan and Yukino’s relationship is not developing in the romantic way she expected. Rather than passionate lovers, they behave like two people assigned to correct each other’s flaws, supporting one another out of responsibility. Komachi helps Yui understand that responsibility and affection are not mutually exclusive: just as hunger and enjoying good food can coexist, the couple’s corrective efforts may eventually produce happiness and romantic sparks. Yui accepts this and decides to wait patiently.
On her day off, Yukino stays home, but she becomes concerned about Xixi after noticing the cold weather. She calls Yunshan to remind him to protect the baby, only to hear that Xixi has been crying restlessly because she is teething. Yunshan is also exhausted after being repeatedly awakened during the night. Believing he may not be properly following her childcare plan, Yukino immediately goes to his home to check. She finds Xixi asleep and Yunshan visibly sleep-deprived. When he tries to insist that he can manage, Yukino orders him to sleep and takes over caring for the baby, revealing a more openly stern and concerned side of herself.
After sleeping for about ninety minutes, Yunshan wakes to a phone call from Xixi’s mother, Dong Yunjin. Yukino is playing with Xixi while rain falls outside. Yunjin hears the baby’s voice and jokingly assumes that Yunshan and Yukino’s relationship has progressed rapidly, misunderstanding Yunshan’s use of “Mom” to coax Xixi into responding. The conversation ends with Yunjin teasing Yunshan about calling her “Grandma.”

Character Developments and Interactions

• Yukino Yukinoshita: Her perfectionism and tendency to distrust others remain central, but she begins practicing care that is less about perfect execution and more about accepting reality. Her concern for Yunshan and Xixi leads her to visit without being invited and take responsibility when Yunshan is exhausted.
• Dong Yunshan: He demonstrates a thoughtful understanding of Yukino’s psychological struggles. He accepts imperfect results and seeks to guide Yukino patiently rather than force her to change. His exhaustion also shows the limits of his own ability to manage everything alone.
• Yui Yuigahama: She initially views the pair through a romantic lens and is disappointed by their lack of obvious romantic progress. After talking with Komachi, she becomes more optimistic and recognizes that affection may be developing through their mutual support.
• Komachi Hikigaya: She provides the key insight that correction, responsibility, enjoyment, and emotional happiness can coexist.
• Dong Yunjin: Her playful phone conversation introduces comic relief and highlights the family’s tendency to misinterpret Yunshan and Yukino’s closeness.
• Yukino and Yunshan: Their relationship is built on mutual correction, practical support, and responsibility rather than overt romance. Yukino’s decision to care for Xixi and force Yunshan to rest shows their growing trust and emotional involvement.

Significant Themes

• Perfectionism versus acceptance: Yukino must learn that sincere effort does not guarantee perfect results, especially in childcare and adult life.
• Helping others responsibly: Yunshan believes that people should act when they have the ability to help, rather than postpone action until opportunities disappear.
• Gradual personal change: Deep-seated flaws cannot be corrected instantly; improvement requires patience and repeated experiences.
• Love expressed through responsibility: Although romantic sparks are not yet obvious, Yunshan and Yukino show concern through practical care, reliability, and willingness to shoulder each other’s burdens.
• The limits of individual effort: Yunshan’s exhaustion and Yukino’s intervention demonstrate that even capable people need rest and support.

Chapter Summary: Yukinoshita’s Correction Method

Plot and Key Events

Mr. Yukinoshita and Dong Yunyan discuss the recent conflict involving their families. Dong emphasizes that enemies should remain worthy rivals who help one another grow, rather than opponents crushed through unfair or violent methods. He warns that adults should not use “adult methods” against children. Mr. Yukinoshita agrees, though his silence suggests guilt.
After Dong leaves, Mr. Yukinoshita opens the briefcase Dong brought and discovers a cake hidden inside. He realizes Dong was responsible for the earlier incident but also recognizes that Dong’s actions were measured rather than malicious. While eating the cake, he decides to warn his daughter Haruno about the dangerous side of the Shinonome-related situation.
Haruno initially explains that “Shinonome” is a common surname, but her father tells her to stop investigating anyone connected to it. He reveals that Dong Yunyan is connected to a family involved in entertainment venues and other potentially dangerous businesses. Before the conversation can continue, a sunglasses-wearing man appears, takes the phone, and reassures Mr. Yukinoshita that the misunderstanding has been resolved. He leaves an envelope containing supermarket coupons as an apology.
The man explains that he only eliminates opposition and does not interfere with how others choose to live. Mr. Yukinoshita interprets this as a boundary rather than a threat: Haruno may continue acting as she wishes, provided she does not cross certain lines or involve adults in the conflict.
Haruno learns that Dong Yunyan’s unusual abilities developed while pursuing his girlfriend, rather than through an assassin-like or criminal background. She imagines that he left his original family to build a new one with the woman he loved. His limited communication skills and extreme methods are presented as the result of someone focused on protecting his own happiness rather than manipulating others.
Haruno decides to stay temporarily at Yukino’s apartment so she can distance herself from troublesome social connections. However, she makes clear that she intends to continue pursuing her own interests, including Dong Yunshan. When her father realizes that the Shinonome individual she investigated is a young man, he becomes anxious that Haruno’s interest may be romantic.
The chapter then shifts to Yukino Yukinoshita, who is trying to determine how to “correct” Dong Yunshan. She considers changing clothes as a way to organize her thoughts, but recognizes that coercion would be dangerous because Dong has begun displaying symptoms of dissociation and an unstable sense of identity. She considers medication and physical treatments such as electroconvulsive therapy and transcranial magnetic stimulation, but concludes that such methods are inappropriate: Dong is not severely ill, is not conventionally depressed, and professional treatment would be required.

Character Development

• Dong Yunyan: Demonstrates restraint, reliability, and a clear personal code. Although he is capable of intimidating action, he distinguishes between protecting someone and interfering with another person’s life. His cake and supermarket coupons reveal an unexpectedly practical, domestic side beneath his intimidating reputation.
• Mr. Yukinoshita: Reveals his anxiety and sense of responsibility as a father. He worries about his daughters’ safety, beauty, intelligence, and family background, yet hesitates to interfere too forcefully. He also recognizes the limits of his relationships with his daughters.
• Haruno Yukinoshita: Shows intelligence, confidence, and a willingness to test boundaries. She understands the meaning behind Dong Yunyan’s warning and chooses to continue pursuing Dong Yunshan within the limits he established. Her interest in Dong Yunshan appears increasingly personal and possibly romantic.
• Yukino Yukinoshita: Treats Dong Yunshan’s behavior as a problem to be analyzed and corrected. However, she recognizes that force could worsen his dissociation, suggesting growing awareness of his psychological fragility and the consequences of her methods.
• Dong Yunshan: Although he appears only indirectly, he is characterized as intelligent, attractive, high-achieving, physically capable, and disturbingly amused by others’ suffering. His dissociative symptoms create uncertainty about his identity and behavior.

Major Themes

• Boundaries versus control: The central conflict is not simply whether one person will interfere, but where acceptable concern ends and domination begins.
• Adult and child methods: The adults agree that mature, powerful figures should not use their influence to crush younger people or manipulate their lives unfairly.
• Family responsibility: Mr. Yukinoshita struggles to protect his daughters without alienating them, while Dong Yunyan protects Dong Yunshan without completely controlling him.
• Love and unconventional devotion: Dong Yunyan’s extreme behavior is reframed as the result of pursuing love and building a new family, complicating the distinction between obsession, loyalty, and protection.
• Correction and mental health: Yukino’s attempt to “fix” Dong Yunshan raises questions about whether another person can be corrected through force, treatment, or manipulation. His dissociation suggests that coercion may deepen rather than solve the problem.
• The contrast between intimidation and domesticity: Dangerous figures are repeatedly shown engaging in ordinary, practical acts—bringing cake, using supermarket coupons, or maintaining a household—making them more complex than their reputations suggest.

Important Character Interactions

• Dong Yunyan and Mr. Yukinoshita: They negotiate the rules of their conflict and establish mutual limits. Dong’s words reassure Mr. Yukinoshita that the confrontation will remain controlled.
• Mr. Yukinoshita and Haruno: He warns her against investigating the Shinonome connection, while she probes for more information and interprets the warning independently.
• Haruno and the sunglasses-wearing man: Their brief encounter demonstrates the power imbalance surrounding the situation. He calmly defines the limits of his interference and leaves an apology, asserting control without openly threatening her.
• Haruno and Dong Yunshan: Though they do not directly interact in the chapter, Haruno’s continued interest in him becomes a major source of tension. She sees him as an intriguing “free little mouse” rather than someone to avoid.
• Yukino and Dong Yunshan: Their relationship is framed as a correctional struggle. Yukino wants to change him, but his dissociation makes force psychologically dangerous and leaves her uncertain about the proper approach.
