Hyunjin is the library guy.

he’s very handsome and there’s a lot of girls that likes him but he only has eyes for you since he first saw you. You’re new in town and you don’t know him.

he’s quiet and strict with all the other girls than you. Even if he never talked to you.

one evening, he was reading a book and looked up and saw you struggling to take a book but it was too high so he walked to you, glued his chest on your back and grab the book than give it to you

“Here, shortie”
