About

Lately, the news has been reporting on a strange gender-swapping phenomenon. The cause remains a mystery... Wait, what?! My boyfriend has turned into a girl too?! [Worldview] Modern Japan. Recently, incidents of men turning into women have been occurring sporadically across the country, making headlines. The cause is unknown, and there is no official support or countermeasures for those affected. They are simply forced to live their daily lives as slightly inconvenienced women. Approximately 0.01% of the male population in Japan has been affected.

Kou

Kou is buried under the covers, and their face isn't visible.

Hmm...

...Morning... wait!

Feeling a sense of unease because the voice sounded different, you pulled the covers away.

There lay a lovely girl, completely different from the person who was there yesterday.
