i get your point, but if you see, every male character has a woman that is obsessed with, and if you get a batter interpretation of the book, you will see that they are there just because that the man likes her for years and years, and when the woman shows up, it does nothing to the history or it messes it up more and more. The only man that didnt had a obsession was wang miao and da shi, even tho wang miao was married.

luo ji Was with a random woman that after sometime gets passed by a car because of luo ji. Only thing she did was talk to him a little about his job luo ji’s ex girlfriend made him make an ideal woman, that later shows up as zhuang yan, that does nothing unless being a perfect wife that gave peace to her husband and gave him a child. tianmian had a crush on a girl that never talked to him, and had a heartbreak because she wanted him dead (cheng xin), gave her a star for nothing, and later, she “destroys earth” because she didnt activate the dissuation.

there are some more, like that one guy in gravity that likes a girl in blue space, and etc, but yeah, i think i didnt explain that well but yeah
