Dear Kim Karin,

                I don’t know how to explain this, but I think I already fall in love with you. I wait for you every day in front of the school gate to see you come to school. For several years I become prefect, I never feel happy because I need to do a same routine every day. However, after you been transfer to Busan , I feel too excited seeing you.
