"Seeing you with her just worsens my pain..." ------ Kelly, lives in Busan with her older brother, Jimin. She has spent her whole childhood being good friends with the one and only... Kim Taehyung since 2nd grade. But they had to move out to Seoul because of Kelly's mom job application. It was hard for Taehyung to cope with her being gone.. Now she's in a popular high school located in Seoul called One Step. Yeah kind of a weird name I suppose. I guess I can say that Kelly and Taehyung met again. Eyes locked in with each other at each side of the hallway. But he kinda acts differently now and.... Taehyung has a girlfriend. But Kelly loved him all this time. Can she love him?
