well it's a yuri series so, just monopolize her, who cares?
it's not something like it's a females orgy or a cuck story
and the whole virgin thing is lackluster since she already established it only counts on males in ch1/2, so a married lez couple or a female only playgirl is still technically a virgin by uni's standards
which depending on your interpretation, is either the very best or the very worst of things.
at least shy!girl is becoming better and the whole love triangle plots were only fakeouts.
