Saejin's love for soccer drove her to apply to an all boys school in order to play the sport close to her heart. With the help of her best friend Chanyeol, she gets accepted and immediately moves in. But will pretending to be a boy be harder than it looks?

And what will happen when someone grows closer to her heart than the sport that she cherishes so much?

Saejin's cluelessness on the difficulty of being a boy will lead her to making some decisions - And only fate knows whether they are good or bad.

*Characters* 

Bae Saejin 

A pleasant eighteen year old with a witty intelligence. She's clever and slightly sneaky though she's ignorant when it comes to the little things. She's kind and considerate and her gentle personality makes it easy for you to get along with. She's best friends with Chanyeol and has known him forever. She loves soccer with all her heart and is going as far as to dress up as a boy and go to an all boys school in order to play on a team. She's determined and strong and optimistic all the while.

Park Chanyeol

Chanyeol is bright and entertaining and fun to be around. His joyful personality and contagious happiness can turn any frown upside-down and he loves to make people smile. Though he's tall and can seem awkward, the only awkward thing about this Happy Virus is his lack of coordination. He has known Saejin since they were born and helps her get into an all boys' school.

Lu Han

Luhan is kind and friendly behind the dull expressions that give off an intimidating aura of unpleasantness. He's sweet and caring and grows close to people easily once he figures out if he can trust them or not. If he doesn't trust them then he's distant, cold and futile, making them feel as unwelcome as possible. 

And frequent appearances from the rest of EXO, of course. :]
