Im Taeyeon ( You ) - You, a 17 years old girl who aren't girly like other girls since you've been taught how to fight since you were small. Your father is like a secret agent,  your mother is a police while your older sister is a spy (yep, like Black Widow lol). Your father asked you to find a boyfriend because he don't want you to be forever single because you've been in house like 16 years. Yes. You took home-schooling. Your father decided to transfer you to Kyungnam High School. You are not really interested in this thing if you were having a boyfriend, he has to be tougher than you. Is that possible?

Park Jimin - A 18 years old boy whom has a mascular body but actually a sweet, kind and cute boy. He said that he don't know how to fight (really?) so his schoolmate bullies him everyday. He always wanted a girlfriend  who can protect him, but the problem is, is there any girl like that? Actually he's hiding a...secret.

Im Jinah (Nana) - A spy (secretly) without anyone knowing. She is 22 years old and got a boyfriend named Bang Yongguk who is also a secret agent. She looks chic outside but actually a cheerful person. She treats you like a princess but she doesn't like you being close with Jimin because he seems...weak.

Bangtan Boys/Bangtan Sonyeondan/BTS - A group that consist of 7 members : Rap Monster/Kim Namjoon, SUGA/Min Yoongi, Jin/KimSeokjin, J-Hope/Jung Hoseok, V/Kim Taehyung, Jungkook/Jeon Jungkook. All of the members are good looking and knows how to fight except for Jimin even though he's a part of them. They always protect Jimin from getting bullied outside of the school but not in the school since they are from different schools.

Author's note ; Hey everyone! I'm back with a new story lol. I know that I haven't update my other stories but I'll do that later, don't worry. : ) The reason why I wrote this story is because when I'm trying to sleep, I got this crap idea lmao.
