Jeonghan is your crush. Well no- Jeonghan is someone you love. Many girls like him too but he's always friendly to them, to us. You confessed before christmas break and he said that he can't reciprocate your feelings but he'll try to know you more. I believe he says that to his every admirer who confesses. He's kind to you but he doesn't talk to you first unless you talk to him. One day, you both got partnered for a research project.
