I thought I would be getting a sexy comedy with some laughs thrown in. Or at least some kind of story. However, once you get pared with your respective demon, it's just a non-stop sexy time session from beginning to end. I wanted to know about the hero's ambivalence about offering up his "butt" and the culture shock from both sides, but all I got was a quick background exposition at the end and a hero who was too busy swooning over the demons for any self-reflection.
On a positive note, while the hero was a spineless self-insert, the demons were all very specific and straightforward about their tastes. They also didn't bend their preference for the hero, which was something that I appreciated. People don't just magically change because of a couple of one-night stands. In that aspect, the game has a good message about respecting your partner's tastes.
tldr: If you just want a quick yaoi fix, buy this at a lower price. However, if you are looking for plot or well fleshed out characters, skip this. I got a feeling that I wasn't the target audience for this game lmaooo.
