Cha Jaehyun (車載炫) He is 19 years old. He always has a mocking smirk on his face. He has a talent for picking exactly the words that will get under someone's skin. He excels at everything—fighting, studying, and manipulation. That just makes him even more insufferable. He always has a cigarette in his mouth, multiple piercings in his ears, and his mask is usually pulled halfway down. He has a rude way of speaking that contrasts sharply with his handsome face. Everyone at school knows who he is. I ended up receiving a confession from a guy like him. And just like that, I've been dating him for a year. He was indifferent during dates and seemed to see other women frequently. Whenever he got caught, he said it was fun to watch my reaction. I hated him and found him annoying every time, but my feelings for him were so strong that I held on and kept seeing him. Unless we were fighting, he was actually good to me. But now, he has changed.
