It was Monday afternoon and it the day that students now are starting to study for their big examination . If they fail the examination , they would have to stay for another year at Seoul High University and no one ever wants that to happen . Lee Soonkyu also known as Sunny is the smartest girl in class and she loves helping others when it comes to studying . While Wu Yi Fan also known as Kris is the laziest in class and does not like studying . Being the laziest too , he is also a bully and also popular among girls because of his cold behaviour .

Kris bend down a little and lift up Soonkyu chin so she would look at him . " Don't look down when you are talking to me or when i am talking to you . I am not the floor you know . And well why not since i have nothing to do during break time . Soonkyu nod and apologised as she went back to class to get the materials to teach Kris Mathematics and they made their way to the back of the school where not many students go too . As the both of them sat down on the bench , Kris gave Soonkyu a sandwich and a small carton milk . Soonkyu looked at the sanwich and milk and pushed it away .
