Kim Jihyun, a 17 year old smart girl, who is known as a rich girl at school. She hates being called rich girl because the people at school knows her parents. Yes, her parents. Her parents are known everywhere. They even have a company named after their daughter. Her older brother, Jinwoon couldn't stand his own parents wealth so he moved out. But, there is a rule. When your kid moves out in your household, you're going to get married. Young or old. When her brother moved out, he was getting an arranged marriage to a Korean American girl named Jessica Jung. They just got married last year because his parents planned it. 

Jihyun has already moved out with her best friend, Kim Joonmyun also known as Suho, what people call him at school. She knows that her parents are going to announce her marriage to a guy who she doesn't know or a guy who she already knows and that she doesn't like. She is hoping that she marries her best friend because they've been best friends since they were in diapers. She is hoping that her parents set her up with Joonmyun because they know that their daughter likes him. 

Suho knows about the arranged marriage thing that her parents have. When he found out that his best friend was going to move out, he was hoping that her parents set her up with him. He has loved his best friend ever since they met.

Suho has his own group called EXO-K. Of course, he is the leader of the group. His other 5 best friends are Byun Baekhyun, Park Chanyeol, Do Kyungsoo also known as D.O, Kim Jongin also known as Kai and Oh Sehun. Jihyun is really good friends with the group and she will hang out with them once in a while but mostly hang with her best friend. 

EXO-K has a rival at school and they're called EXO-M. The leader of the group is name Wu Yifan or also known as Kris Wu is what people call him at school. His 5 other best friends who are in the group with him is Kim Minseok also known as Xiumin, Luhan, Zhang Yixing also known as Lay, Kim Jongdae also known as Chen and Huang Zitao also known as Tao. Jihyun will also hang with the group except Kris.

Both group leaders hate each other. The members of the group doesn't know why they hate each other but they don't bother to ask because they know they're going to get yelled at.

Jihyun HATES Kris. She can't stand him. If Kris walked over to her, she will immediately walk away from him. She couldn't stand him being close to her.

Even though Jihyun hates him, her parents LOVES him. They will try to set him up with their daughter even though she doesn't allow it. Her parents will send Kris over to her apartment where Suho is also living. Finding the place where Jihyun goes since her parents has "stalkers" watching her everywhere if she was ever in trouble.  

Jihyun will be slowly starting to develop feelings for Kris. That means that she will be slowly pushing her best friend away with out her knowing. Even though Kris acts like he hates her, he actually likes her. He'll just pretend to hate her because she hates him. 

Who will Jihyun end up with? Her best friend? Or the new guy that Jihyun's parents set her up with?
