The heir to a top wealthy family, Yin Kuiqing, is gentle and gentleman on the outside, but selfish and pathological on the inside - he is obsessed with his childhood sweetheart Han Lan, while showing affection for his decent lover; he can be gentle to everyone, but he is mean and violent towards Han Lan. He thinks he is "dirty", but he is paranoid and refuses to let go.
The gentle and forbearing Han Lan gave him her entire youth and sincerity. She saw how he loved her most, so she would rather have her dignity crushed than leave.
The two clearly loved each other deeply, but one was imprisoned by humiliation, and the other was carried by humiliation. In the end, everything was spent, leaving only a love that was rotten to the bones.
They were supposed to be the happiest couple, but they were ruined by his selfish hands.
Intention: to make money.
