from the redhead that double crosses the mc to the fuckall crazy yandere that deals with money and shady shit behind the scenes that chases after the mc's to the brother that's playing a game with the mc. only different here is that classroom mc doesn't have a guy she likes and wants to protect nor is she physically violent. instead, she just wants to inherit a company but can't because of her gender. kinda dumb for a backstory tho ngl. if her father was any smart, he'd invest in his daughter inheriting if she's better than her brother lmao.

at least secret bother mc doesn't use and dispose of people to the point where they all betray her. instead, she's genuinely loved by many because she tries to protect them

lol nope, i can assure you that's not the case here
