He set a boundary. I don’t really see it as an issue. They could have come up at any point in time to apologise. This happened in the second chapter and we are now in chapter 7. At literally any point in time, any one of them could come and apologise to both of them and continued being friends. He’s not being an asshole. He’s sticking up for someone he loves and showing people where his boundaries lie. I don’t see that as a bad thing at all. It’s admirable. I know so many people who put up with friends trash talking their partners or something that their partners have or something that their partner identifies as and they just sit back and let it happen. My ex was like that actually. I WISH he had told them all to shut up and not talk to us unless they were ready to apologise and not be horrible to me and mean it. We broke up cause he put his friends opinions of my race and stuff over his love for me. Furushima did the absolute correct thing and it’s an absolute green flag. Sticking up for your partner is bare minimum. Saying no to mocking a person is bare minimum.
I don't think he is, he has a right to want genuine and friends and people he can feel safe around
we don't really know much about the guy friends yet so we don't know for sure but to be honest I find it equally bad if your female friend is being a bitch and harassing a guy and you sit there and do nothing or atleast call her out

Furushima is kind of an asshole, I mean I get he likes whatever his name was I forgot and stuff but he kinda ghosted his friends?? I know his friends were kind of assholes aswell but we mainly saw it in the girls.
