keep em thumbs down cummin

I don't believe they've ever said The girl can't cheat....
It's just taking traditional Japanese / Chinese drama plots which often includes the guy cheating with a "better"woman but the girl always gets her revenge by hooking up with someone even better than her last man . That's always the case but I think she is actually putting the revenge in revenge making both the cheater and the woman he cheated with truly pay in one way or another. Both the woman and the man are equal and they both get equal punishment's

This is “cheating” men not all men.
The author included the female (transmigrated singer) who cheated with her feelings and wanted both men.
Yeah society should be uplifting each other but this is a drama pertaining to a cheating gender. The author is most likely female and can better state from her POV.
I can understand if you feel there should be more statements for both genders (if anyone cheats then they should go down) but I think the author better explains in a female POV.

I agree with last comment, the cheates are men, but the women are bitches (and a cheater for last one) so...

I agree with what you're saying, that she mainly seems to focus the men, but if you look back on all of the stories she actually focuses on the men AND women that do the cheating. This is a fairly common theme in many Chinese comics, the cheating men are dicks and the girls they cheat with are bitches, and the one getting revenge makes them both pay.

Sorry, meant to dislike. My finger slipped

You didn't even bother to read this, or you'll notice that the cheating women end up very poorly, indeed, and sometimes DEAD.

i mean, usually in these system stories, the chars have a specific type of world they are sent to
she is in a system that specifically sends her to a world with a cheating man soooooo ╮(￣▽￣)╭
