My Refrigerator Turned Into A Dungeonうちの冷蔵庫がダンジョンになった

The skills and the dungeon are interesting, the secondary characters are average, not corton, but not well developed either. But because of mc this novel is very bad for me.
The world of the novel is banal but just as interesting, but not developed properly (there may be few chapters yet). The problem of the novel in mc, like most Japanese novels, in this novel he is not just a beta mc, but also dumb, very dumb, he earns millions selling mana stones, but at the same time he still worries about society's opinion about his unemployment , while living in a rented apartment, all in order to buy a house, or build somewhere in a convenient place, to at least hide your dungeon from surprises, like a landlord, but no, this moron whines about the fact that he is supposedly unemployed with him there is no profession, and this is bad for society and how people will look at it (with millions in their wallets).
and then it occurs to him to get a job as a massage therapist (why and why ?, only the author's holey head is known). An overly person who can buy a small house, put a refrigerator in it, upgrade to the level of Superman and shit on opinions and everything around, live as conveniently as possible, does some kind of crap, which is even very bad for plot development. About relationships, I can only say that at the beginning, this is beta mc with a dead brain and 0 ambitions.
