so this manga is basically about... girls who f*cked up their life?
anyway, I don't think it's the brother, the physique is kinda different
but hey, I do hope it's the brother, it's much better than her being raped by a stranger
but damn, that Yuusuke, he talked about how dangerous a social media was to her, and then proceed to let her say something that could reveal her identity... he didn't even bother using some kind of alias for her account
Yuusuke is the real jerk here
