Half a year earlier, Sakuta Azusagawa met a rabbit‑costumed girl in the quiet corner of the library. Since that moment he has been content with his partner, Mai Sakurajima, who is the same rabbit girl. Yet when his first enigmatic crush, now grown‑up Shouko Makinohara, returns, it complicates his bond with Mai. Things worsen when he encounters a junior high Shouko in the hospital, battling a serious disease; oddly, his old wounds flare whenever he is close to her.
Because Shouko"s strange circumstances seem tied to him, Sakuta must confront his mixed emotions, whatever the outcome. With a girl"s life hanging in the balance, what will he decide? He must choose, for their lives depend on it.
