Yoshifumi Matsuda, who has been bedridden for over five years due to illness, reflects on his life with regret from his sickbed. He believes that his current situation is his family’s fault, and if he had been born as a woman, life would have been more enjoyable. In that moment of thought, he hears a voice from nowhere, and Matsuda’s consciousness is engulfed in darkness. When he next wakes up, he finds himself in a room in the familiar apartment he used to live in, transformed into a baby girl.
