The poor heroines are always alone, pure love
Lin Xiao's mission is to save pitiful heroines who have suffered terrible abuse. But each time she transmigrates as a vicious female villain, completes the important task of saving the heroine, and is ready to retire after a job well done, the pitiful heroine she saved tries to do the sort of thing only a villain would do to her, ruining her chastity.
Weren't these heroines supposed to be pitiful? How are they all sweet on the outside and dark on the inside?
If you flirt, you have to take responsibility. If you don't want to, the heroine will force you to!
