I'm not star-rating it yet, as I want to see more of the art. I do know the story is very good based on the excellent Live Action drama that aired last year with Yui Aragaki as the clean-machine contract-wife who loves and needs to be needed and Gen Hoshino as the clean-freak virginal nerd-engineer who needs a housekeeper that lives up to his standards. They slowly fall in love, though their personalities will have to work through issues. Coworkers and a best friend and family add to the dramatic events and the humor. Not wild about the art style up front, but it's growing on me. Story should be very good.
