What follows is an encounter that threatens to tear him away from Sodegi Kana, a girl who reciprocates his feelings for her. It is this meeting with another girl, who shares a deep, yet unknown connection with Shinji, that beckons in his inevitable transformation into one of the "invisible people" himself.

Sakura Kousuke is a boy who strives to throw away a past mired in regret. He transfers to a new school for his second year of high school, believing it will give him a chance to come clean.

A coming-of-age story, both light-hearted and dramatic, by the author who would later give us "Jitsu wa Watashi wa".
