Tang Hui, a genius Chinese medicine doctor, was suspected and betrayed by her fiancé. The root cause was the absurd youthful tooth mark hidden on the back of her neck.
In high school, she was mean for a moment, forcing 18-year-old Fang Lvying to split his personality, leaving a fateful scar.
Many years later, Fang Lvying became a top tennis star. He sought medical treatment for a serious arm disease and reunited with her, and the gentle personality fell in love with her.
Unexpectedly, the ex-fiancé was unwilling to get entangled, and the unexpected stimulation awakened Fang Lvying's paranoid personality.
Past grievances, hatred and unresolved love are intertwined. Fang Lvying, who is dominated by his personality, deliberately pulls indifferently, trying to make Tang Hui understand the pain of that year.
However, true love has long been ingrained in the relationship between them day and night, and revenge will eventually be in vain.
