A group of friends enjoying high school together in South Korea. The boys, Aron, Ren, JR, Baekho and Minhyun has known each other as long as anyone of them can remember. Ren, JR, Baekho and Minhyun met So Ah when they started 2.nd grade. But the day she started (in the middle of the semester) Baekoho was sick. Being shy and quiet she attracted Ren and they became good friends over a day. He introduced her to the others and they also became friends. Aaron however, was in a few grades higher than the others but soon got the chance to meet So Ah. Ever since then they have hung out together, creating a family of their own. Now they are 16-18 years old and are facing a soon-to-be love triangle between So Ah, Aaron and Baekho.  

Ren/Choi Minki

Ren is a boy that when first looked upon, he may seem weird and 4D (which he is) but that is however not what he always is. He's a person that will listen carefully when you tell him your problems. The person that everybody turns to when they feel down and need someone to talk to is always Ren. Since everybody tells him about their problems and come to him for advice he was the first to know about So Ah's crush on Baekho. He is still the one she turns to when she has problems that she can't tell Baekho about. People always tend to be protective of Ren something that he doesn't always like since he can obviously take care of himself!
 

Hwang Minhyun

Minhyun is the hothead of the group, he always gets himself into fights and arguments with others. He is always teasing everybody in the group and play pranks on them. His main target has always been So Ah and he drives her mad with all of his pranks and teasing. Minhyun is, despite his teasing, the most protective of So Ah. He loves her like a sister and doesn't really let any guys get near her. Mainly because he knows that So Ah loves Baekho, he doesn't think anyone is good enough for her. He's also the laziest person among them but when it comes to play prank the energy is ongoing. 

 Kim Jonghyun/JR 

Jonghyun is the “leader” of the group even though he's not the oldest, he has a way with people. When he says something they listen and do what he says. He is also the smartest among his friends and has the best grades. However, he never speaks or brag about his grades. When the group is a difficult task, that is when JR steps up as a leader. He's very shy around girls, except for So Ah ofc. So Ah always tries to introduce him to different girls but he will always reject the offer saying that he needs to focus on school and so on.

Aaron Kwak

Aaron is the oldest in the group of friends, he love his dongsaengs a lot and would do anything for them. He has been moving back and forth from Korea to America and has recently moved back to Korea. When you first meet him he seems to be cold and distant towards you but once you get to know him he's actually really sweet. He can also be a real ladies man (when he wants to) and always gives you compliments. He meets So Ah for the first time in in a couple of years and is completely starstruck, he immediately falls in love with her.  

Kang Dongho/Baekho

Baekho is a cute guy that really cares for the people around him. He's almost always smiling and and he's a little bit clumsy but that he can wave off with being extremely handsome. The person closest to him except for his group is So Ah, they have been close since 2^nd grade and she would always help him when he gets into trouble, which happens a lot.... Baekho is, despite his clumsiness, popular among the girls in his school. He's really nice towards everyone and it helps him when he causes himself trouble.

Han So Ah

So Ah is a cheerful girl full of "aegyo" and she's the one with the brightest smile. But when she's around people she doesn't know or in a big group of people she tends to be the quiet and shy one. She has been around the boys since their 2^nd year in elementary school, the reason for this was mainly Baekho, she fell in love with him the first time she saw him. She started following him and helping him with things and they grew really close. But still she hasn't confessed her feelings for him, Baekho is the only one oblivious to the fact that So Ah loves him. All the other boys noticed it from the start.....
