It'd be funny if they were kids/teens. They're all adults, working jobs, in college etc. There's no need for his brother to move in and constantly do shit to interrupt his life and act all controlling. It's not funny or sibling coded, it's obsessive, he expects seung to just say yes to everything he does/enjoy it.
Esp after the bit of freedom you got is at college away from family and just having fun with your lover. ☠ like he's trying to live his life and here comes his brother just intruding for no good reason.
Wait why do we hate the brother? He’s kinda funny LOL
He raised our boy, comes to check in on him, is jealous he only pays attention to chaejun, wants him to move in with him because he’s worried, moved to the bottom floor when he said no - yes he is cockbloxking but it’s so sibling coded LOLLOL
