The first Doukutsuou kara Hajimeru Rakuen Life: Bannou no Saikutsu Skill de Saikyou ni!? novel (English subtitle: Climbing to the Top with My Almighty Mining Skills!) is atrocious. There is not a single ounce of rhyme or reason to anything that occurs within it, starting from the very beginning when he’s ostracized for having a rare ability that everyone around actively refuses to research.
It only gets worse from there, as for no discernable reason he immediately begins finding new types ore that just so happen to possess the exact magical ability necessary to solve any issue that may arise. Can’t cast any magic because of a low mana pool? These tunnels are laced with thousands of kilograms of mana-expanding ore! Someone appears with a lifespan-shortening curse? Looks like this island contains ore that both dispels curses and extends your lifespan! It’s infuriating, and you’d probably be better off just reading/watching Isekai Nonbiri Nouka instead.
Kusushi no Majo desuga, Naze ka Fukugyou de Rikon Daikou shiteimasu meanwhile is a pretty standard ‘opposites attract’ semi-romance livened up with irreverent characters and a bit of a twist: The protagonist takes on requests to break off engagements/marriages, only for the couples to end up reconciling instead. It’s pretty fun.
