"an insulting and informal term for a person who is habitually unhappy, irritable, easily angered, or disagreeable, and often spreads their bad mood to others".. do you need example??
If I remember correctly, his the one who confront with Na Hae-soo, about her relationship with Mincheol', belittle her, like she was sa shackles(something like that)for Mincheol.. correct me it I'm wrong'..
can anyone remind me who's that grumpy bastard?? What's his role in this manhwa??
