If you find it, plz tell me too!!
It's not a manga/manhua but a light novel.
I thought I had it but it's not here in my reading list(novelupdate). Sorry.
Disregard, it was similar but not really(?). Dude inherited a restaurant from uncle that act as a place to get energy (for the nonhuman being to travel)...My Hotel Is Famous All Over the World
Oh Thanks, I feel like I've read it before...
I felt like I read this kind of troupe, but a bl version…so similar
