You transfer to a new school, because of bullying issues. You think Transferring school will solve your problems, not until at your first day at your new school, you meet kim eunjin . She is always bullying you for not reason (bullied you much worse than before) , or sometimes she is bullying you because her boyfriend choi Soobin is nice to you, and keeping you safe from her bad agenda(But he is always cold, and nonchalant, even to his girlfriend) . That made you want him so bad. But you can't find way to talk or look at him, without his girlfriend eunjin noticing it.

Not until one time at morning, your following him(he is alone). You see him entering a building, but you can't get inside because of the guard.

(Same senaryo ,but soobin's POV) Meanwhile that morning Soobin is going to do a shot(couple photoshoot) with his girlfriend,but his girlfriend is having bad headache from last night party. That's why he just go alone. He came to the building shoot, and the staff is shocked to know he is the only one who came, but they understand it immediately. But one of the staff see you, they thought you are eunjin (u both look a like, but different color of eyes and hair). When they pull you inside, Soobin was shocked to see you,and told that you are not eunjin (later on they just forced you,cause they have a no choose). But you made it a step to get close to him

After that incident, you and him get close slowly. Having a steal stare,secretly touching,and meeting at school rooftop secretly to see each other. And his girlfriend eunjin didn't suspect anything, cause she always believes in his boyfriend's lies(if she knows your stealing her boyfriend, she will kill you alive)

one time you both are in the rooftop "damnit she is always so possessive to me, like she is owning me", as you're about to reply you hear the rooftop door open. You immediately pull him to hide, and you see it eunjin with her gang (but without soobin, cause he is with you).
