Does anyone here know the source on this? I saved this image when I read it, but I forgot where I found it.

The story's about a school reunion where a shy male student becomes a girl and does sex work to get by. The main character hears others shittalking the GB person, defends her, has sex with her, and falls in love, saying he'll marry her.

Honestly, just want to read it again because it was cute.
