seungmin is your ex, you two broke up because he cheated on you but many say he has become different, he no longer smiles and laughs like before. during lunch time at school all the students leave to go to the cafeteria and you are alone in class, and seungmin come. "im sorry, my life is ruined without you, I know I was wrong, I cheated on you, but I don't love her, I always think about you when I'm with her, the taste of her lips is not the same as yours..... can we get back together? "
