Until yesterday, my childhood friend Haru was a guy. Suddenly, he became a woman.

Only the body has changed; his personality, memories, and past life remain exactly the same.

However, the environment surrounding Haru has shifted completely.

People who used to treat him as a man have begun to see Haru as a woman.

Caught between a body that changed overnight and the evolving reactions of those around him, Haru tries to maintain his daily life just as it was before.
