okay but if shirabu fucks other girls in front of u, does that mean if you have sex with another boy he would literally berate you for it?
you would be an actual moron to think you would even be able to get a boy past the entryway of the house. niichan doesn't even let you go out with friends or anything.
if, by chance, you attempted it. it wouldn't even be a lecture or him berating you. no, he's not above smacking you around and humiliating the ever loving shit out of you. he'll tell the boy you're a sick little freak who is only fucking him to make her niichan jealous bc she's a disgusting little niichan fucker!!! he'll fuckin lock you outside naked if he has to. anything to make you learn the lesson that you're not to fraternize with boys. ♥️
he's not gonna have a whore of a sister running around ruining his rep before he even gets a chance to graduate medical school!!!!!
