Considering this is a hentai game, too many of them don't have any sex with us (player character). For those featured in the story, like Juliette and Red Battler this isn't much of an issue, but the rest it's like "oh yeah come to my harem, and we'll assume we had sex but we won't show it even though this is a hentai game". Also, one-line scenes generally aren't very interesting, informative or enjoyable. To be fair though, since the player time commitment is minimal, I feel I can't be too demanding lol.

Agree with above that Agate and Jennie were among the most "rewarding" but they fall into the very few scenes where we're actually having sex with them.

BTW, I seem to be one of the few who detests Bunny but that's a personal preference thing lol.
