'here they go again.' You thought

Your classmates were AGAIN teasing you because a boy, Lee heesung who is your junior found another way just to see you.

Heesung,that one hot junior who had a crush on you and didn't care to hide it. He surely became shy whenever he was near you tho. He would come into your classroom to give his notes to the teacher as an excuse to see you.

And that's why you were getting teased because today this happened again.
