Doyoung is 27 years old, your teacher. he is cold, strict, heartless, single. he is also handsome, so many students & women like him. but he still chose to remain single.

One day, he taught. suddenly, you come in and he stops talking & looks at you, & the students look at you too. Doyoung just looked at you holding the marker. his face was colder than usual. then he said in a cold and firm tone, “Why are you late, Young Miss.” as he waited for you to answer.
