Kim Taeyang isn't an ordinary person. Born autistic, he is always teased and became a bully victim in school. However, he is good in sports especially soccer. Everyone acknowledged this but they still dislike him.

But... things changed when he entered senior year. A girl came up to him and confessed to him on the very first day of school. However, being slow, Taeyang did not understand what the girl had meant. Will Taeyang feel the same way as the girl?
