There always is that one really special friend that’s a boy. Someone you can be stupid in front of without feeling self-conscious around. What if you made him over into the most popular guy in the school? What if even YOU fall for him too?

Choi Chaeyeon and Kim Myungsoo are best friends and they have been ever since they teamed up and chased the bully out of the playground back when they were two.

Now, they are finishing up their sophomore year in Gangnam High School where Chaeyeon is the girl people say "hi" to in the hallways and gossip with between classes. Myungsoo, on the other hand, is probably the most nerdy, smart, uncool guy in school, complete with the oversized glasses and extensive vocabulary. 

Throughout the two years in Gangnam High, Chaeyeon spots Myungsoo being pushed around and shoved into trash cans daily. She decides to change that when they transfer to Seoul Performing Arts High School the next year. 

The summer before the transition to SPAHS, Chaeyeon carries out the most amazing makeover on Myungsoo to change him from a dork to the most popular boy on campus.
