Background / History

Su Yumei grew up as the “good child” in her parents’ eyes and never went through an outwardly rebellious period. Her restrained upbringing left her privately curious about experiences and role-playing scenarios that conflicted with her cultivated image as an educator. 56 80

As Lin Che’s Chinese teacher, she appoints him class representative, giving them a legitimate reason to meet frequently. She initially relies on hypnosis and the pretense of hypnosis to act on feelings she is otherwise too embarrassed to acknowledge. 6 27 55

When her mother pressures her over blind dates, Su Yumei asks Lin Che to pose as her boyfriend. Although troubled by the teacher-student boundary, she chooses him over a blind date and brings him to meet her family. 24 25 48

Her relationship with Lin Che gradually shifts from secrecy and shame toward open acceptance of her feelings. After being confronted with her actions at the school, she acknowledges her desire to obey and please him despite the risk to her reputation. 129 130

Appearance

Su Yumei is a mature, curvaceous woman with a notably gentle, scholarly presence. Her usual professional clothing and composed posture reinforce her image as a dignified teacher, while her private outfits often reflect the contrast between that public persona and her hidden interests. 27 37 236

• Slightly curled or wavy long black hair, often framing her cheeks. 27 37
• Fair, delicate face; narrow, expressive eyes; cherry-colored lips. 27
• Curvaceous hourglass figure, described as more voluptuous than Su Mengxi. 80 133
• Commonly wears a conservative teacher’s uniform, black skirt suit, black silk stockings, and high heels. 27 36 236
• Uses collars, animal-ear accessories, and other role-play attire in private. 55 56

Personality

In public, Su Yumei is gentle, dignified, patient, and highly professional. Her students see her as a refined and knowledgeable teacher, while Lin Che experiences her as especially nurturing and attentive. She takes academic matters seriously and readily slips into a teaching mindset when discussing language or writing. 27 78 127

Her private self is far more insecure and repressed. She is easily embarrassed, initially attempts to use hypnosis as emotional cover, and struggles to reconcile her desires with her identity as a respected teacher. Once she feels accepted by Lin Che, however, she becomes increasingly willing to explore role-play and submission. 55 79 81

Su Yumei is notably compassionate and forgiving. She worries about Gu Yilan, tries to understand Lin Che’s other relationships rather than demand exclusivity, and ultimately forgives Su Mengxi after their conflict. 134 135 159 160

Story Role / Major Arcs

Early Teacher–Student Secret

Su Yumei’s private attraction to Lin Che first emerges through her hypnosis attempts. She makes him her class representative, creating repeated opportunities for contact, while her proper school image begins to conflict with her hidden desires. 6 12 27

Fake Boyfriend and Family Visit

To escape pressure from her mother’s blind-date arrangements, Su Yumei asks Lin Che to pretend to be her boyfriend. She brings him to meet her family, and their staged relationship becomes increasingly genuine. 24 25 48 49

“Secret Boyfriend” Persona

Su Yumei creates the “Secret Boyfriend” trigger so that Lin Che can supposedly become her boyfriend only in private. The arrangement collapses when she learns that Lin Che was never truly hypnotized, forcing her to confront that her feelings are real. 55 79 80 81

Acceptance at School

Lin Che brings Su Yumei back to school at night, where she is forced to confront the disparity between her identity as a teacher and her private submission. After they narrowly avoid discovery by a security guard, she becomes less willing to deny what she wants. 128 129 130 131

Acceptance of Lin Che’s Other Relationships

After Gu Yilan discovers her relationship with Lin Che, Su Yumei fears she will be rejected as an outsider. Gu Yilan instead accepts her, and Su Yumei later listens to Lin Che explain his ties to Luo Xue and Ye Mingyan without demanding exclusivity. 132 133 134 135

Conflict and Reconciliation with Su Mengxi

Su Mengxi attempts to use hypnosis and jealousy to control both Lin Che and Su Yumei. Yumei pretends to be hypnotized, helps expose her sister’s schemes, and finally stands up to her rather than quietly yielding. 153 157 158

Despite the betrayal, Su Yumei forgives Su Mengxi after seeing her remorse. The sisters reconcile and agree to remain in Lin Che’s life together. 159 160

Later School Return

During a later return to the high school for a National Day event, Su Yumei resumes her composed teacher persona in front of others while covertly giving Lin Che control of her private role-play device. She later incorporates the Orchid Pavilion Preface into an unusually charged calligraphy lesson with him. 236 237 247 248
