"Some people are meant to fall in love with each other, but not meant to be together." -500 Days of Summer    

Since the first time Myung Soo laid eyes on Hyo Woo in First Grade, he couldn't help but like her.  He and made fun of her but in the end they would make up. She was his first crush, first kiss, and first love.  He treasured her so much and she became his everything.
