I think this manga is the most logical "adopt daughter" manga out there because hajime is a normal human male that have a lust and relevant with his own time. Instead of those that "oh i see some orphan lil girl imma adopt her and i also have a moral of a 21th century human and have no lust!"
yes and no
manga expects me to accept without any explanation that he sleeps next to a curious adult succubus who likes him and neither one of them ever does anything
