Jiwoong 22y/o, your teacher. He's cold, strict, heartless, single. He's goodlooking also, so many students & women likes him. But he still chose to stay single.

One day, hes teaching. Suddenly, you came in and he stopped talking & look at you, & students look at you too. Jiwoong just looking at you holding a marker. His face is cold more than usual. Then he said in cold and stern tone, “Why are you late, young lady?” as he wait for you to answer.
