No it is not. The main character is female. And she's just a normal girl before being transported to a different world and becoming an innkeeper. Not a Mary Sue as well but she's really good at chess which is like her main thing.

It's one of my favorite web serials of all time. Have you ever wanted to read a story and wished it never ended because it's so good? Try the Wandering Inn! Still going strong even after 9 million words. I started it during the Covid lockdown 2 years ago and was enraptured by it for a few months. The story is an isekai (people from our world transported to a different one) in a fantasy world where people gain levels and skills like an RPG. Has inspirations from The Lord of the Rings, DnD, anime, and other nerdy stuff.

If anyone is interested check out The Wandering Inn. I was confused as to how Erin (the main protagonist) related to Trump lol
