Yeah but he never apologized for bullying him during this time (not mentioning attempted SA towards him and how he never even showed concern for when Jun's soles was hurt due to glasses inside his shoes and when his arms was broken). He just said shit like you're my god and followed him to his dorm room like stalker. He gets forgiven after he protected Jun from the acid attack. He hurt himself to save Jun but he never apologized so I never felt satisfied

Guys I don't want to be a party pooper but you should lower your expectations for this manhwa. At the end of the novel, there's no truly remorse and regret from ml, there's is not a properly chasing arc either. There's almost zero character development from both of them.
