You are one of the troublemakers in class, and because of that you always get into trouble, but the teacher has to keep you because of your good grades

Today you get another punishment, and you have to clean the lab room with the president class

Your class president is Seungmin, he always tries to be patient with you because of your stubborn attitude

When you were in the lab with him, the two of you were silent without talking, until you picked up the beaker and accidentally dropped it

Your hand is injured because it was hit by shards of glass, and Seungmin walks towards you while squatting down looking at your hand

"You are really careless"
