Lucy: Why do you always get angry whenever I talk about boys that crush on me? Why?
Kris: I don't know
Lucy: You don't know? You even beat up Sean for attempting to kiss me, what the hell is your problem?!
Kris: (eyes closed) I love you, okay?
Lucy: You love me? You, Kris, love me, such a lie! You told me yourself that I am not your spec, so what the hell are you spitting out!
Kris: I love you, I don't know, I just….
Lucy: You just what?!
Kris: Nevermind
Becca: Kris, do you love her or not! (Kris walks away) Kris!
Lucy: I don't just get Kris, today he says he loves me, tomorrow he says he doesn't.
His actions are confusing
