A OR B

Hye Joo was given the opportunity to choose who she loved and who she doesn't. What if she's stuck in the middle of both options?

Hye Joo is a high school teenager, she's known to be a role model for classmates and a bit immature at times.

Kang Ari is Hye Joo's classmate, a flirty person and an extrovert who loves bothering people and annoying the crap out of them.

Nam Oh Ji goes to the same school as Ari and Hye Joo but he does not attend the same classes as them. He's also an extrovert, his personalities make people like him more, and he's a friendly soul.

Kim Ju Da attends the same class as Hye Joo and Ari but she's an arrogant high class bitch. She has many friends and people backing her up, but loves to pick on others.

What goes on when all these people's lives get involved into a love triangle?
