I'm lmao at the downvotes you got. You're very much right; they are in manga. I've yet to find a single one where the girl has feelings for the guy and she's like: "Oh shit, he has a boyfriend? Aight let's move on then."
No I'm talking about how girls are villainized in my previous comment, I should have typed how I predicted this lmao, my bad.
They are always villainized in manga, how they are characterized to be hoes that either invoke jealousy or attempt break break mc and their love interests
It was a plot tool that was overused, it's always the cutiepie girl that needs to have an urge and boldness to feel entitled to say whatever she wants, the type of mythical girl that she's the embodiment of princess that needs to break up mc and their love interest so when she succeeds, all will be rainbows and unicorns in her eyes
F4cking knew it, girls will always be hoes
