Heroine: Su Wan
Before rebirth: Due to family calculations and childhood trauma, she suffered from post-traumatic stress disorder (PTSD) + dissociative identity disorder (DID). When the disease broke out, she was irritable and indifferent. She took the male protagonist's efforts for granted, which ultimately indirectly caused the male protagonist to die in a car accident while trying to save her.
After rebirth: Waking up with the memories of his previous life, the time is stuck on the day when he was "sent to the hero's hospital for forced treatment by his family". The disease is still there, but his mind is clear - his only goal is to pamper the male protagonist who "humbled to the point of falling in love with her" in his previous life and become the happiest person in the world. Externally he is a "difficult psychopath", but internally he is a "clingy and protective little coward". He will remember all the male protagonist's preferences, put down all defenses in front of him, and even "protect" him in his own way.
• Male protagonist: Lu Shiyan
The founder of the country's first psychiatric research center, he became the "top psychiatrist in the country" at the age of 30, and is known in the industry as the "living dictionary of mental illness." He has a cold, restrained, and extremely rational personality, but he is obsessed with Su Wan. In his previous life, he was the "family doctor" of Su Wan's family. He watched her change from a beautiful girl to a sick hedgehog, and guarded her silently for many years. Even when she scolded her, "Don't follow me" and "You are disgusting," he never gave up. In the end, he died because of a truck that blocked her.
