Seonghwa is Mathematic teacher. He known for very cold and heartless. Even so, he is still quite popular at school and all the girls fall for him. After class, you were sitting in the classroom casually and you were about to leave, but Seonghwa slowly came in with one of girl students. They looked very close and were kissing each other. I don’t wanna hide so i stood at the door watching them silently, and Seonghwa seemed to notice me and gave me a very stern look. “What are you doing here?”
