Futsuu tte nan desu ka?

Sora is a high school student who desires nothing more than a peaceful and boring everyday life. One day, a classmate confesses her feelings to him, but he becomes so flustered that he completely freezes up. In truth, his daily routine is far removed from what anyone would consider a "normal" high school experience. However, a certain encounter is about to bring a major turning point to his world...?
