This is a story inspired by the teachings of Freud and Horney. Both the heroine and the hero suffered from severe childhood trauma. In the end, the heroine split into three personalities: a cold adult, a weakling with stagnant growth, and an aggressive killer. Only in this way can the three people who don't know each other do their own things, and she can feel safe, otherwise she will collapse and commit suicide.
The male protagonist would faint in a slightly claustrophobic space. He had irresponsible parents and had several life-threatening injuries when he was a child, which caused him a serious sense of alienation and world-weariness. He hates adults, and his good memories only exist before the age of 10, so he has pedophilia.
The cold side of the heroine is married to the hero. They have past stories, but they cannot be intimate in the most intimate space, even if they say an innocuous word.
In the end, the male protagonist's father could not stand the oppression of his money-worshiping wife and gradually fell in love with the cold and knowledgeable female protagonist; the male protagonist was immersed in the other side of the female protagonist - the childlike fairy and could not extricate himself...
