Bobby and Hanbin are best friends, almost like brothers one could say. One day Hanbin's cousin, Min-ji becomes part of the 'fam' as she is their new roommate. However, Bobby is immediately uncomfortable around her. Only to find out she's mentally ill and takes pills to stay right. Hanbin is way over protective with her. Bobby and Min-ji are two completely different people with different mindsets. From two totally different worlds, but when their worlds collide, what's bound to happen?

When the school's most popular playboy gets dared by his group of friends to make the cold hearted new student, Hayi, fall in love with him, he thought it be a piece of cake. Given only a 100 days, Bobby will have to make her love him before the time ends. Bobby had never failed to get another girls attention nor has he ever fell in love with one. But will the new girl change that?

I saw his brown eyes and at first i thought-they are so small ....but i kinda liked them.I said "Ok" and wanted to go but he stopped me.I turned around and i look at him once again.That was my mistake because he smiled showing his white teeth with two in front a little bigger. I literally felt that Earth stoped moving.I couldnt breath,i couldnt move,i couldnt even take my eyes of him.His smile hit me like tunder lighting and i was helpless........
