Author really dropped the ball here, all he had to do was give one reason why the MC was still in disguise because its a strange thing to gloss over.
Lol, all MC had to do was say a few sentences:
- "My original purpose to disguise myself is finished, but my female disguise has become such a brand name in this country for my dungeon clearing services that it makes no sense to start from scratch. And, if another group ever comes after me, they'll never be able to figure out my identity and hurt the people I love"
-"The girl I saved just lost her entire entire family. I'm afraid what she would do if she discovers the last person she had to rely wasn't who she said she was...and I don't want to leave her all alone. There's no harm staying like this for just a little while longer"
But nope, quiet MC wants to stay an enigma, even to the readers.
