Yeah, exactly that, well said.Hmm.. Guess I misunderstood it somewhat then. I was never fooled into thinking this would be a vanilla romance novel, it says pretty clearly the game's dark at the game page.
Still I got the impression the relationship between MC and Rumi would have a big role in the game and they would experience a lot of the story/adventure together, maybe I was wrong about that.
If Rumi is just largely an irrelevant NPC with some few optional fluff scenes then I suppose the NTR(if it even is that) rape scene will hardly be that impactful and it's whatever.
So more like classic JRPG with everything centered on the FMC being thrown into all sorts of dark sex stuff.
edit: I don't think people thought this would be a yuri only game, dev, more like a game with a decent amount of lesbian content (MC and Rumi as a couple) and a lot of other stuff including dark scenes.
