it does seem like an irrational and unfair decision but the big brother wouldn't change his disgusting mind if he started to live outside. at least this way he might feel ashamed looking at his mom's face everyday. given how woojin apologized in the middle of all that, she's also saving woojin from the unnecessary embarrassment he's in, also giving him the space and freedom he needs.

idk, the mom kicking out the gay son instead of the noodles for brain brother is kinda irking me. i understand noodles for brains wouldn’t survive out in the real world and might end up behind bars, but he wants to be homophobic so that means he can handle the weight of the world as well.
