He hated her...

She despised him...

Neighbors since birth, childhood friends turned sworn enemies find themselves in eachother's shoes, LITERALY!

What would you do if you woke up one day as the person you hated most? The answer is simple, ruin their lives...

Him: Kim Jong In a.k.a Kai

Kim Jong In or Kai, as all his friends call him, is the typical quarter back of the varsity football team and high school jock. He is a senior in high school. He has developed sort of a bad boy image, which has made all the girls love him even more. It is a known fact that most girls in his school fantasize about him. Kai is perfectly aware of this too and is very arrogant and cocky. He has no concerns whatsoever other than, partying and having a successful football career. Not to forget his head cheerleader "girlfriend" Kim Hyuna. Everyone assumes that they will be prom queen and king. Kai has a lot of friends, everyone loves him. However, his best friend in the whole wide world is Lee Taemin.

Her: Jung Hye Ri (You)

Hye Ri is (yup, you guessed it) the outspoken nerd of the school. You are a senior in high school and are actually quite pretty, and many boys in your school would agree with that. Its just that your personality is not so good. You have strong opinions and are not afraid to speak it out. Most boys would want to "get with you", if it weren't for your personality. You only have one real best friend, Choi Injee, whom you've known since the 6th grade. You are on the varsity girls soccer team, so you are acquainted with the girls on your team. All of them are just normal, not too nerdy and definitly not popular. You hate two people in this world, you arch nemisis Kim Jong In and his superficial girlfriend, Kim Hyuna, together they never fail to make each passing day a living hell hole. But, it okay because you love to read and write. Literature is by far you favorite thing. You hope to attend Seoul University as a literature major after high school.

Choi Injee

Injee is a very shy, cute girl. In fact, in front of people she's not comfortable with, she doesn't take at all. People in her school are under the impression that she is mute. However, that is not true. In fact, when she is around Hye Ri she is very easy going and talks quite a lot. Hye ri and her are so close, that she practically lives at Hye ri's house. You are super loud an Injee is super quiet, people say you balance eachother out and maybe thats why you two are so good together.

Lee Taemin

Taemin is known for being cute, this is how he gets all of his girls. He is actually a very big playboy and is very promiscuous. He loves to party and have fun. When Kai and Hye Ri were childhood friends, Taemin was also very good friends with them. When they started to drift apart, he wanted to stay with Hye Ri but he chose Kai instead. Taemin looks at hye ri in a very brotherly way. No one knows this, but Taemin always watches over her, making sure she is in no real danger.

Kim Hyuna

Hyuna is head cheerleader and most popular in her school. Her biggest life goal at the moment is to be prom queen with her super hot boyfriend Kai, the perfect king. Bassically, Hyuna's a . Everyone "wants" to be her, so she thinks. However, its more like everyone is afraid of her and her power. Those who disobey her go through hell. There is only one girl who is not afraid of Hyuna, no matter what she does. That is Jung Hye Ri. The fact that Hye Ri is the only one who still fights back to her, gets her so angry.
