Well, that was a fun game. It's definitely one of the more lighthearted NTR games, although the plot seems to be going deeper and deeper into the serious NTR territory, abandoning the layer of context that Ruru's actions were to keep the MC to herself. That said, from my understanding she's very popular, so it's to be expected Patreons want her to be doing more traditional cucking activities over the more ambiguous tone of the early sections.
Maybe the issue is that I don't find the MC that bad? I skimmed through the forum (it's quite short for a game of this quality, but I guess the NTR tag does that), and apparently people find him unlikeable whereas I just view him as the equivalent of an immature, generally decent high schooler.
I know the dev has said they don't want to give any details about the endings, but if they're willing, I'm curious if there will be an ending where Melvin just decides not to be with anyone? Obviously, they'll be friends, since anything else would contradict the game's tone, but it'd be nice to see Ruru's overarching plan fail just for the fun of it. Or would she immediately enslave and rape him if he actually rejected her in the end?
