Seojun is your friend since childhood, he is also your first love, just as Seojun also actually loves you but you both don't want to admit your feelings for each other, until high school you were always bullied by the punk upperclassmen because Seojun didn't want you to always be bullied, he joined the bully gang so you wouldn't be bullied again "Why did you break our promise? You said to Seojun""Sorry, I didn't mean to break the promise we made," answered Seojun
