Well, if u think about it. He is really poor so he doesn’t have a washing machine or anything electrical/expensive. So he wouldn’t know how to use something he doesn’t have. Plus, he wouldn’t know the difference between washing ordinary clothes and expensive clothes ヽ(￣д￣;)ノ even I don’t
He didn't separate colored clothes from white as well as wrung the clothes wrongly base on the panel. At the very least one good household skill is something he should have in order to increase his charm. I mean he considers himself a hired worker there and not someone kept so being useless isn't appealing. Even if not now at least I hope he can learn the skills.
I think if you're poor and have cheap clothes you won't separate white and colored clothes since you don't care about discoloration anyway, as long as the clothes are clean and you can quickly wear it again
I mean last chapter shows that he can cook but he's using expired foods because he can't waste it, i think he has the household skill, but his poor life gives him a certain habit
I expected the uke to be someone who's good at housework since he's living alone as well as he's frugal. Why did his setting become "cuteness and super strength is the only thing he's good at" I hope his farming skills is good at least even if housework skills is miserable.
