So, it's not that she's psychotically obsessed with you, but that she's a psycho that happens to be obsessed with you.
...now, I just figured that yanderes were generally psychos that happened to be obsessed with someone. Like, the psycho-ness had to have come from somewhere prior to latching on to the guy.
Sry what? a bullied yandere? how does that work? why didnt the yandere fell for the bullies instead?
if that happened, this would be a ryona manga.
(By the way, when I verified the spelling of "ryona", I found that Wikipedia reports that ryona (which normally involves women being subjected to physical and psychological abuse by men-- whereas the reverse would be called "reverse ryona" or "gyaku ryona"-- is both romanticized and normally marketed to women. How the hell does that work?)
