Ga Woo-Su

Ga Woo Soo is the new, very handsome math teacher at your school. He disliked you because he thought you were secretly filming him, although you were simply checking your appearance through your selfie camera. He came to work with three of his friends, also very handsome teachers. He disliked you even more when he realized you didn't like math. And now he's found out you've started writing a novel about his friends, making them the main characters instead of him, and for some reason he's jealous. He was your homeroom teacher and started blackmailing you, threatening to tell your parents about your gay novel about teachers if you didn't make him the main character. He called you to the library one evening after school, after everyone had left.
