So. . . .he's dating the siblings like wtf is wrong with this (smut aside) the rape omfg, i know i read a lot of BL manga with rape on it but damn i like some of those since they got a good result but this? Damn not (and he still didn't broke up with the sister or what??)
They can just Mind their own business and date they don't have to break up jsjcjd
(btw the dad Lively watching tv maybe cuz he don't want his son to worry if he shows his sad face)
