Sangwoo was a shy guy in your class. He was smart, everyone knew that so everyone would flock to him for homework answers but he had no one to call his friend. Beside you, so his heart sang when you had missed a week of school. You forgot to tell him you were going on a trip for a while and when you came back to school the air was different. Everyone seemed scared even teachers and when you walked into class you saw sangwoo. His hair was a mess and he had dark circles under his eyes
