Two boys and two girls. "Unfortunately, you can't tell your heart who to love." "This is the sad side Ah Young-a...If you can't tell to your heart who to love you usually end up hurting." Best friends who fall in love. "Usually...This one who take your heart love other right, Nana?" "Yea...But you know...The other usually is not the right one." Did they make the right choice? "Maybe..." "Maybe...This story can have that happy ending we all want, but I don't believe in it, Ah Young." Are they scared from what is going to happen? "Maybe I believe...But Maybe this person don't believe and maybe I'm scared." Is it too late for second chance? "It is too late, Nana...It hurts every moment when you remember this smile and every fucking moment together." "What the life is?...I hate this question because I know the answer...What about you, Kim Ah Young?...What you think?"
