That'll do for me, even if I wasn't into the described scenario.
Which sounds fun.

Ditto that. I love the author's work so far. Then of course there is modern dungeons. That's definitely my favorite genre.

There is a decent handful of these "super-overpowered individual in a modern world with dungeons get outed when they are unknowingly livestreamed" stories.

This one at least is willing to lay it out straight with a simple reason, and doesn't appear to be trying to turn it into a romantic comedy or harem novel.
