One day, returning home, I found an unknown girl at my front door.

After a brief conversation, I learned she was the man who used to be my best friend.

Apparently, she had been transported to another world, turned into a woman, and had finally managed to return.

I decided to live with her for a while, as she claimed to have nowhere to live.

——Wait. Now that I think about it, what kind of man was she before she went to the other world?

This is the story of a transgender (TS) girl, formerly a saintess, who returned from another world.

The male protagonist has been brainwashed by the TS girl into believing she is his best friend.

This novel contains psychological Boys' Love (BL) elements.

This is a novel where a jaded TS girl is healed by the easygoing male protagonist, and as she grapples with various worries, she gradually warms up to him.

This novel alternates between the male protagonist's perspective and the TS girl's perspective.
