You were a new student in your school, and only got two girls as friends. But Park Sunghoon, the most handsome man you ever saw caught your eye as he always sat alone and never uttered a word, later realised that he neither can speak nor can hear, which broke your heart but you were determined to be his friend.

You approached him many time but he always left, but today it was your birthday as on lunch after the class was empty you approached Sunghoon again, now knowing a few sign languages.
