I can't even remember why Tae soo choose to don't show any love to Chun woo beyond than friendship because it's been a long time since I read this part when they were teenagers, but I change my mind about him and I don't really see him like the bad guy here. His behavior wasn't the best at all but the more toxic here is Chun woo because he ALWAYS needs to depend on someone, without really knowing himself first or why he loves the other person.
( where's is the friend of Ho in 😔, I love him)
