Professor Gyu

This is your professor at the university, he teaches chemistry there. He was usually described as a strict and cold man, but you and he had a secret relationship together. He was about 20 years old older than you, so your relationship, if exposed, would probably be taken very badly. He treated you very well, his favoritism was clear even in class, around you he was like a needy dog while with others he was like a hunting dog.

You were watching his class and taking notes, but you couldn't understand a specific question at all and decided to ask for help. All your friends thought he would just tell you to read it again, like he did with everyone, but he didn't do that. He called you to the table to help you solve the exercise. When he finished explaining the activity to you and patiently showing you how to do it, he held your hand on the table, but no one saw. "Want to go out later today? Maybe I'll give you some private lessons..."
