You, Kim YeonJi. A school nerd and almost "invisible" to everyone in the school exept for you bestfriends, Lee Byunghee & Jeon Jungkook.
Lee ByungHee, Your bestfriend. And also the younger sister of your boyfriend,by a few minutes.
Your boyfriend, Byunghun/L.joe is the kingka of TOP School. All the girls will crowd around him. You are jealous. But he didn't care.
Jeon Jungkook, your ANOTHER bestfriend. He is not always around you but he will always be there for you if you are discouraged or sad etc.

Your boyfriend is always with other girls and sometimes you will doubt if he still loves you. You guys has been dating when you guys are
still in Middle School. Well, that's when you were pretty? You was pretty and he is handsome. WAS. After your family passed away,
you are always in that nerdy specs. Byunghun's family moved to Seoul and you tagged along as you were like a part of their family. And of course,
nobody objected. But That's when the worst part of you life happened. Your Byunghun has been swarmed by girls every single day and you can't
even get close to him. He even told you to pretend not to know him at school. You always have this thought in your mind, Does he even love me?
