Yoon Jin Byul is a spoiled princess who likes pink…a LOT. A music lover as she is, she loves to sing and dance. Her earrings is even a G-clef. She is the total girl. Cosmetics is her known specialty. Jin Byul is practically inlove with Lee Donghae.

Her bestfriend is Lee Eun Ri. She is a photographer who loves to dance. She is not as much of a girl as Jin Byul is. In fact, she almost never wears accessories; with the only exception of a silver heart necklace given by her dad. She has a crush on Lee Eunhyuk. Donghae and Eunhyuk are cousins who are volleyball varsities. Donghae is hot, as you might say. He’s popular, handsome, and rich. He’s also a leader for the volleyball team and at the same time, he’s the class president. Eunhyuk, well he’s the more reserved type. He’s a TOTAL sleepyhead. Unlike his cousin, he isn’t that popular. But almost everyone in school thinks that they are both boyfriend-material. Two girl bestfriends dreaming about two boy cousins. The boys have no idea… the girls are doing everything not to be found out. But what happens if fate suddenly took the wrong turn and they get paired up with the wrong person? And then another person comes. Would it still be the simple equation as it was before? Or would it be a frenzy of complicated formulas?
