Background / History

Yumian was raised in the Carlos family under its hereditary curse. His first transformation occurred at age ten. Even before then, he struggled with empathy, pain sensitivity, and a volatile temper; his mother repeatedly attempted to teach him kindness before eventually giving up. After her death, Elaine taught Yumian to accept the curse and turn its dangers into strength rather than deny them. 33

The curse causes unpredictable beastification, emotional instability, visible fangs and beast ears, and sometimes a complete loss of human consciousness. Yumian initially regarded these traits as frightening but useful, adopting the image of an arrogant and dangerous Carlos heir. 33

At Elaine's wedding, Yumian immediately recognizes that the Shi family has substituted the intended Omega. He and Lindsay begin hearing Shi Sheng's unspoken thoughts, which warn Yumian that Noah and Lanreese intend to exploit him. Although initially hostile toward the apparent impostor, Yumian gradually acts on Shi Sheng's warnings. 1 3

Appearance

Yumian is a fair-skinned, blond Omega with lake-blue eyes and an ornate, refined style. His appearance becomes markedly more threatening during episodes of beastification. 4 11 21

• Blond hair and pale complexion. 1 21
• Lake-blue eyes that turn scarlet during loss-of-control episodes. 11 21
• Petite build, described as refined and flamboyant. 4 9
• Develops sharp fangs and, at times, beast ears when affected by the curse. 21 28
• Often carries a dagger at his waist. 14

Personality

Yumian is proud, sharp-tongued, and easily angered. Early on, he treats servants harshly, distrusts Shi Sheng, and reacts aggressively to anyone he believes is manipulating him. He is acutely conscious of his status as the Carlos family's only S-rank Omega and refuses to accept a marriage arranged solely for political convenience. 2 4

Behind his arrogance, Yumian is deeply frightened by the implications of the Carlos curse. He sees himself as a monster who cannot reliably control his body or emotions, and he believes few Alphas would willingly marry someone from the Carlos family. This insecurity drives his initial wish to marry Ning Zhao for practical protection rather than love. 22 23 48

His relationship with Shi Sheng softens him considerably. After Shi Sheng is injured protecting him, Yumian becomes protective in return, accepts the affectionate nickname “Yumi,” and begins restraining his more violent impulses rather than simply embracing the role of a villain. 15 19 34

Abilities & Skills

Cursed Beastification

Yumian's inherited curse can partially transform him into a beastlike state.

• His eyes turn scarlet; sharp fangs and beast ears may emerge. 21 28
• Beastification greatly increases his physical strength and speed; he can pin a taller Alpha to the ground and overpower opponents quickly. 21 47
• The full moon and intense emotions aggravate his condition. 21 28
• In severe episodes, he becomes unfocused, violently aggressive, and may lose human consciousness. 21 33 47
• Suppressant pills and sedatives can reduce or end an episode, though they do not cure the curse. 21 22 29

Combat Proficiency

Yumian received combat training from the finest knight in the capital.

• Fights with a dagger and reacts quickly during attacks by magical beasts. 14 17
• Subdues Viscount Deli after being tied up, binding him with his own tie. 29

Perception of Shi Sheng's Thoughts

Yumian can hear Shi Sheng's inner thoughts despite Shi Sheng never speaking them aloud.

• First hears the thoughts during Elaine's wedding ceremony. 1
• Uses the information to identify Noah's false identity and Lanreese's attempts to manipulate him. 2 3

• Lindsay Carlos — Adoptive elder brother and primary caretaker during Yumian's curse episodes. Lindsay administers medicine, calms him during moon madness, and mediates his arguments with Elaine. 21 22
• Izel Carlos — Elder brother. They argue over Yumian's plan to use a marriage to Ning Zhao as bait for Noah, though Izel acts protectively toward him. 34 35

• Lanreese — Former almost-fiancé and childhood acquaintance. Yumian discovers that Lanreese intended to drug him into accepting a proposal, ending any remaining trust between them. 3 20 21
• Ning Zhao — The Crown Prince, whom Yumian initially wants to marry for political security and because Ning Zhao does not wish to mark an Omega. 14 22

Story Role / Major Arcs

The Substitute Marriage and Noah's Schemes

Yumian is among the first Carlos family members to realize that the Shi family substituted an Omega at Elaine's wedding. Hearing Shi Sheng's thoughts gives him forewarning of Noah's revenge plot and Lanreese's betrayal. Rather than immediately exposing Noah, Yumian deliberately brings him to the Imperial Ball to observe what he will do. 1 3 8 12

Imperial Ball and Shi Sheng's Protection

During the magical-beast attack at the Imperial Ball, Yumian draws his dagger and follows Shi Sheng into danger. A beast specifically targets Yumian, but Shi Sheng pushes him away and suffers a severe neck injury in his place. The incident fundamentally changes Yumian's attitude toward Shi Sheng. 14 15 17

Moon Madness and the Crown Princess Proposal

As the full moon worsens his condition, Yumian catches Lanreese attempting to drug him and nearly kills him during a violent episode. Lindsay intervenes with suppressants. Convinced that his curse makes ordinary love and marriage impossible, Yumian asks Elaine to arrange a marriage to Ning Zhao. 21 22

Accepting the Carlos Curse

After Elaine's beastification, Yumian explains the family's curse to Shi Sheng and admits his fear that no one could love a “monster.” Shi Sheng's reassurance prompts Yumian to reconsider his belief that the curse makes him unworthy of affection. 33

Hovis and Sky Street

Yumian's unresolved feelings for Hovis lead him to repeatedly visit the Capital Police Bureau. On Sky Street, he violently retaliates against an Alpha who assaults him, nearly escalating from self-defense into attempted killing before Shi Sheng and Hovis restrain him. He later uses the return of his dagger as a reason to demand that Hovis visit him personally, deciding to pursue the Alpha despite believing their relationship cannot succeed. 47 48
