Looking for manga

[BzzBzz]

I remember it very vaguely, I don't even remeber if it was manga or LN/WN :/

It's typical "kicked out of hero party" story.
After getting kicked out of the hero party because of something related to girls in that party MC goes to "travel the world". In next town he clears the dungeon in company (or did he rescue her mid-dungeon?) with another girl. Then dungeon disappear from the world and become MC's "pocket dungeon" that he can "install" any place he wants and freely teleport in an out from any place in the world.
When hero comes to that city he finds big hole in the ground where dungeon was.
Every time hero tryes to do something he finds that that was done "just a couple days ago" by some anon. etc. etc.

Any ideas?

dang, that's harder that I expected since I wasn't sure whether it is in my dropped list or still reading trash list

can't remember this part since I already dropped it

"pocket dungeon" that he can "install"

but there is a scene for this part in this one

he finds big hole in the ground where dungeon was.
