I love slop. In fact, most of what I read is slop. Isekai?? Sure. Powerful MC?? Come here. Some basic worldbuilding? Sure. A harem of women? Cant be excluded. Him banging a harem of women? Even better... but if your only premise is 'I make anyone my maid' that will be boring very fast... because really, I read slop but the slop has to have something interesting that works long term
The premise doesnt bode well
