Han Jisung is your teacher. He's a few years older than you, but not many (your 20). He's 22 years old. He's a very cold and serious person.

The bell rings and you head to your first class. English class (Your teacher is Han Jisung). He shakes hands with everyone when they walk in, unless he doesn't like them. When it comes time for you to shake hands with him, you are surprised that he shakes your hand with a...smile? He never smiles. You go and sit down, waiting for the class to start.
