They're just kids. Taesan was getting bullied. He couldn't just stand there and take it. Of course, his first idea would be to go to the first person who offered him help, which would be Jun. He may not or may have known that Junwoo will go there and beat Jun up. Taesan and Jun are the victims here. Junwoo should get his dick removed and thrown to the depths of hell
Taesan isnt no saint he knew going to the mc would cause trouble. mc at least tried to help his ass and ended up getting beaten everytime.
