I Have Decided to Go Look for My Father

Lin Xi spent 14 years at this family and never did figure out why she had always been mistreated.
She finally learned that she was living in a cliché novel with radical moral standards.
Her mother was the female lead and her “father” was the male lead. Before the male lead fell in love with the female lead, he had belittled and was abusive to her in all sorts of ways. He even offered her up to others and, finally, the female lead had intimate relationship with a strange man.
The male lead fell head over heel in love with the female lead after that and expressed that he did not mind the child. Nevertheless, the existence of said child was a like a thorn in male and female leads’ hearts and it reminded them of their past constantly.
Unfortunately, Lin Xi was this child that should never had been born.
In the extra, Lin Xi tried to set up her sister out of envy but it backfired on herself and she ended up strangled. The male lead was able to locate the man who had intimacy with the female lead and ruined both his reputation and family fortune.
After 10 seconds of hesitation, Lin Xi decided to leave the family where she was not loved and go live with her own father.
