irl speaking up isn't something easily done esp in a workplace like that. his situation made it harder for him to defend himself and although it is frustrating for us bystanders there's only so much we can do. I just hope he would come to immediately realize he's also responsible in defending himself.
also, their characters is opposite of each other. While the section chief just could care less and seemingly likes to dodge complicated situations, the other one is seems to be someone who takes things to heart and kinda meek (nothing wrong about it). It's probably also bcs they just got into a relationship and only know trivial stuff about each other that it's easier to misunderstand each other. None of them seem to like to be looked down too, one way or another
there's no way that's the ending?!?! Can't I see them graduate first?!?!
