ok, so I get that locals can't go into MC's room without MC's help or at least a copy of his key...but what excuse did he give the landlord and/or his job for why he's gonna be gone for an undermined amount of time? cause, sure, he can probably just bring home some precious metals/gems from the otherworld and not need an actual job anymore, but he'd still either have to explain to someone where the stuff is from or sell it for less money to the kind of people who wont ask, and it'd be REALLY awkward to come home one evening after a couple weeks of isekai tour to find the house got rented to someone else
