Hyoyeon and kai have hated eachother for a long time. Even though they don't really know each-other anymore, kai is extremely popular probably most in the school, hyoyeon was just above average but she was well known for being a tomboy and her good looks. She causes a lot of trouble with her best friends since before she could remember are yuri,tiffany and baekhyun.

Baekhyun has always had a tiny crush on hyoyeon at the back of his heart but he set it aside for their friendship. They were always the 4 best friends but hyoyeon had a cousin she loved with all her heart taeyeon. Even yuri and tiffany were jelous of their friend ship they used to call eachother the hyotae couple when they were young but since they go to different school their friendship weakened a bit. (They live opposite eachother so it's still ok).

In middle school tiffany yuri and hyoyeon were apart of a nine member group called snsd. They were all best friends and most popular in school everyone looked up to them and admired them because of their beauty and individual talents. They would walk through the halls and people would step aside and admire them. But since they went to different schools for high school they broke apart but are still admired, no one can insult them really they have a weird power over everyone.

hyoyeon had a good life ;smart, amazing friends, great at sports, kind, funny, a enemy, a crush(kinda), fanboys, fan girls, she was everything any girl would wish for. A mans perfect Barbie doll. Nothing could faise her.

But What happens when hyoyeons father remeets his best friend from the army,(Kai's dad who is now the owner of a successful company) and they make a few plans for their kids. Will they accept eachother? Will they get along? Will they still hate eachother? Will baekhyun realise his feelings? Will he be too late? What will happen to the four best friends? What will happen to the enemies? Will hyo and Kai's past come back to haunt them? Will hyos world still be perfect or will it break apart?
