Background / History

Su Yu originates from another world and initially experiences life through the perspective of this world's Su Yu while being unable to consistently control the body. He retains his own thoughts and personality but is forced into the original owner's submissive mannerisms, including a mute façade; only in rare moments can he make deliberate movements himself 2 5 6.

The Su family had used him as a substitute for Su Hui in an arranged marriage to Gu Lin, requiring him to pretend to be mute. Though he and Gu Lin were legally divorced early on, they initially continued living together because the divorce could not be announced publicly 3 52. Once Su Yu regains full control of his body, he can speak openly and completes the divorce process with Gu Lin 49 51.

Su Yu later learns that Ye Qingwen is not his biological mother and that he was switched with her real son as a child. Wei Yuancen had found and raised him for several years before Ye Qingwen took him away 94 131. After reconnecting with Wei Yuancen, Su Yu publicly chooses to recognize him as his godfather rather than accept Bai Min’s authority as his mother 139.

Appearance

Su Yu is an Omega whose outwardly delicate appearance often causes others to underestimate him. His expressions can shift quickly from wounded-looking obedience to bright, disarming warmth.

• Pale complexion and clear, emerald-like green eyes 23 63.
• Small and physically slight compared with most Alphas; he is repeatedly described as soft, frail, or rabbit-like by observers 9 35.
• Often wears sunglasses and adopts exaggerated fashion while shopping with Yun Shang 31.
• His mournful, submissive expression is convincing enough that others—including Gu Lin’s grandmother—read him as harmless and pitiful 23 118.

Personality

Su Yu is blunt, restless, and deeply resistant to being controlled. Having endured the Su family’s neglect and bullying, he has little patience for forced reconciliation or appeals to blood ties. He often avoids direct confrontation when his circumstances limit him, but his internal commentary is sarcastic, irreverent, and frequently more aggressive than his outward behavior allows 6 70 124.

Despite his self-described detachment, he is protective of people he considers his own. He intervenes for Yun Shang against school bullies despite being physically outmatched, worries about Lu Heyun’s isolation, and challenges Lu Chengfei whenever he thinks Yun Shang may be taken advantage of 9 30 35 78.

He is also indulgent and easily motivated by food, games, shopping, and new gaming equipment. His forgetfulness—especially with passwords, keys, and schedules—contrasts with his sharp instincts for reading people and provoking rivals 31 59 65 110.

Abilities & Skills

• Lu Chengfei — Lu Heyun’s cousin and Yun Shang’s classmate. Su Yu often scolds and teases him, but also games with him, helps improve his mood, and closely watches his intentions toward Yun Shang 45 51 147.
• Su Wang — Su Yu’s half-brother and former bully. Su Yu secretly deceives him through gaming, openly clashes with him after regaining control, and remains unwilling to forgive their past 14 48 66.
