Background / History

Cao Xi was an S-rank omega and graduate student under Professor Jiang Ying at the Scientific Research Institute. Initially physically frail, quiet, and fearful, he regularly visited Ye Nanxun during lunch breaks, bringing treats for Little Dragon and finding comfort in their quiet companionship. His fear of Jiang became apparent whenever Jiang was nearby. 38

In Ye Nanxun's previous life, Cao Xi was deceived into attending He Lanxue's birthday banquet, imprisoned in the He household with Ye, and subjected to experimentation. In the new timeline, Jiang again brought him to the same banquet under the pretense of helping him relax; Ye recognized the danger and became determined to prevent Cao Xi's past fate. 39 40

At the banquet, several alphas abused Cao Xi at a pool party after he was drugged with a substance intended to induce omega heat. Ye Nanxun rescued him, engineered the chaos that enabled their escape, and took him to the hospital for treatment. 41 42

Cao Xi later helped Ye investigate Jiang Ying's laboratory and his network of omega exploitation. He supplied a list of Jiang's core laboratory members, trusted Ye's plan to remove him from Jiang's control, and eventually transferred to Ye's laboratory as his first student. 57 70 95

Appearance

Cao Xi is a small, slender omega with pale skin and notably clear eyes. During his time under Jiang Ying, he was often described as frail and pale, habitually hiding much of his face in a thick down jacket. 38 95

• His appearance and complexion improve significantly after leaving Jiang Ying's supervision. 95 130
• By spring, he no longer needs his heavy winter coat and appears younger, healthier, and more energetic. 130
• He remains comparatively petite beside Gu Pingsheng even after recovering. 238

Personality

Cao Xi is initially timid, withdrawn, and easily intimidated by powerful alphas, particularly Jiang Ying and Zhu Shixin. His fear is rooted in Jiang's exploitation of omega students and the lack of institutional protection available to victims. 57 58

Despite this fear, Cao Xi gradually becomes more outspoken and resilient. He aids Ye Nanxun's investigation, encourages Gu Pingsheng to report Jiang Ying, and openly challenges Gu when she believes he is neglecting his health or safety. 70 96 136

His recovery brings out a cheerful, blunt, and occasionally mischievous side. He is deeply loyal to Ye Nanxun, whom he views as both a mentor and protector, and becomes increasingly comfortable teasing Gu Pingsheng. 95 130 175

Pheromone Condition

Cao Xi has an abnormal pheromone condition that causes his heat-period reactions to be stronger than those of a typical omega. Song Ren oversees his treatment and requires regular medication and physical examinations. 120 143

• His condition improves while receiving treatment at the Imperial Palace. 130 143
• Ye Nanxun arranges for Song Ren, an elite pheromone specialist, to examine and treat both Cao Xi and Gu Pingsheng. 120 130
• Cao Xi's medical vulnerability was exploited by Jiang Ying and the alphas connected to him. 41 57

Relationships

• Ye Nanxun — Rescuer, mentor, and trusted protector. Ye saves Cao Xi from abuse at the He household banquet, supports his recovery, investigates Jiang Ying with him, and later accepts him as a student. 42 57 95
• Jiang Ying — Former advisor and abuser. Cao Xi once admired Jiang, but came to fear and hate him after learning of his exploitation of omega students and his ties to alpha elites. 38 57
• Gu Pingsheng — Fellow student under Ye Nanxun and later romantic partner. Their initially tense relationship develops into mutual trust, affectionate friendship, and eventually a confession of love and physical intimacy. 96 136 175 236
• Song Ren — Pheromone specialist responsible for monitoring Cao Xi's treatment at the Imperial Palace. 120 143
• Yan Beiyou — Cao Xi respects him as Dream Star's ruler and eventually addresses him as “Master” because of his relationship with Ye Nanxun. 130 174
• He Lanxue — Her birthday banquet became the setting of Cao Xi's rescue from Jiang Ying and the He family's predatory circle. 39 42
• Zhu Shixin — A dangerous alpha who overwhelms Cao Xi with pheromones and grabs him outside Jiang Ying's laboratory before Ye intervenes. 58

Story Role / Major Arcs

Jiang Ying's Victim

Cao Xi's first appearances establish the threat Jiang Ying poses beneath his respectable image. His fear, isolation, and repeated visits to Ye Nanxun reveal the psychological effects of Jiang's control. 38 39

Rescue from the He Household

Cao Xi becomes the immediate victim of the He household's abuse at He Lanxue's birthday banquet. Ye Nanxun risks exposure and retaliation to save him from the drugged pool party, making Cao Xi's survival a turning point in Ye's conflict with Jiang Ying and He Yiming. 40 41 42

Investigation and Transfer

After recovering, Cao Xi provides crucial information about Jiang Ying's laboratory, helps Ye infiltrate Lab Three, and participates in the plan that removes him from Jiang's supervision. He then becomes Ye Nanxun's student, gaining a safe professional environment and renewed confidence. 57 58 70 95

Reporting Jiang Ying

Cao Xi encourages Gu Pingsheng to join him in reporting Jiang Ying, reminding him that Ye Nanxun has promised to protect them. Their decision to act transforms them from victims enduring abuse in silence into witnesses willing to challenge Jiang's influence. 136

Reunion with Gu Pingsheng

After Gu leaves Dream Star to pursue singing, Cao Xi remains in contact with him. When he returns as a successful singer-songwriter, Cao Xi mistakes his confession of love for someone else, becoming jealous and insecure before learning that she is the person he loves. 175 232 233 236
