This honestly is a series where imo, a harem ending could actually be better than a "best girl" ending. Sure you have the main "couple" of Hinata and Yurina, but then literally all the other characters want to fuck Hinata too. And while they may want to monopolies Hinata, it isn't like they hate each other either, and since all of them have dicks now (besides Hinata and Yurina), it could be interesting. It is one of those things which you do not see often, the gender-bending mixed harem where just about everyone is the opposite sex.
