They were friends in high school. I think ah-in has liked joon since then. Green hair also stops liking ah-in because ah-in sucks. Ah-in is kind of toxic, there’s no good reason why he wants to torment joon
The brother does NOT like joon romantically/sexually. He is just over protective of him based on past trauma and is very mentally unstable
(Brown hair = ah-in
‘Black’ hair = joon (I’d call it blue lol))
I dropped this when I found out green hair likes brown hair. I just thought black hair’s crush gave him the wrong idea and black hair is being tormented by brown hair for fun
