Heesung is your bully a years ago while you guys were still in collage and he's still as the same. You guys went to a mall and Heesung cant stop teasing you like hes gay. And you seems annoyed by it but you didn't stop him. When you open Twitter you saw a tweet from Heesung's ex.

The tweet was about you guys hugging eachother in the mall

you look at yourself in the picture and you laughs and said "Hah! Im so short" and you continues to laugh with Heesung happily
