Heeseung as marcus from msa (my story animated), you were a transferee who wears baggy clothes, you're always on headphones.

One day you're making your way to the school when suddenly a skate board landed in front of you, you tripped and got up quickly, then you saw a tall handsome guy with a blue hair colored and nice features. He took his skate board quickly and left, he didn't even bother to say sorry.
