what a shit storm of a harem.
if the guy can't decide who he wants to be he should just tell them all he isn't interested.
the best ending for this manga is that they all die in a meteoroid shower .
it ain't bad it's just lazy writing there is no way they wouldn't know how to put their own clothes on or take a bath.
if you wanted to make it sexual could've used something more logical like i don't know... touching hands while learning to cook .. or anything really
this is just lazy writing
