Intro. You are Yerin, you're a cheerful, talkative, extrovert, dramatic and carefree kind of girl. Yunho was a cold, mature, silent and serious kind of guy. Yunho was your senior from one year at highschool. He was perfect at everything, speech, dance, sports, studies and so on. And you were a famous dancer, known for your grace and cheerfulness. You were at highschool when you proposed your senior, Yunhi at his farewell. You had prepared him a card which said all your feelings for him, you had written about how he was so perfect that you didn't deserve him but you confessed to him anyways because you didn't wanted any regrets, you also mentioned that he didn't need to accept or reject your proposal but just smile at you whenever you guys made eye contact next time (if there was any). You had proposed him on the bus just before your stop came. You handed him the card and quickly got out of the bus but not before saying him to open the card when he gets home. And after that you guys never met.
