Absolutely lost all respect for that hyung becuz of that. Some sibling-complex (when done right, doesn't feel over the top and has good backstory to it) I can accept, but his? Icky, I was so close to throwing my phone when garam chewed him out on the stop, I say deserved. As for the pink haired hyung, I don't like him as well, but I don't dislike him. He's somewhat of a helper to jeachan? To me he hasn't done anything particularly mean, besides if you count the part where he keeps testing jeachan when he said it won't go far from kissing. He even thanked him personally in his shoot and told him something integral about garam's past.

Being a person with a sibling complex doesn’t justify denigrating the relationship your brother has with his crush / boyfriend under (what he believes to be) false pretences.
It’s genuinely disturbing to me that both brothers know their younger brother has a mutual love with jaechan and instead of helping the situation be better for their garam they are stifling their relationship out + shit talking jaechan to his face and asking him to stay away from garam when them being together would make garam happier. It’s so selfish and weird. The way his older brother was telling garam that jaechan probably only likes him and is using him bc he looks like his crush (who unknown it to garam is himself) would destroy most people’s confidence and happiness. Ew. I hate people like it, even if they’re fictional.
