Synopsis: Dong Ane Deun Seonsaeng-nim

Alcohol, cigarettes, men. Ha-Yoon, a 20-year-old repeat student who had been living her life with all the bad things, meets her homeroom teacher, Hyung-Won! Ha-Yoon feels curious about him who doesn't care about the rumors others gossip about and always breaks expectations, and for the first time, she learns of love. *"I like that teacher." "That's not love. You have a lot of delusions at your age."* But unlike other men who would fall for you if you teased them a little, he's the world's most stubborn man, so it's not easy... But it's okay, because I'll break down all those stubborn walls! (Source: Ridibooks, translated)
