The 'NTR is avoidable' in big red letters was here two years ago,
and it still means nothing. It's the same game with the same story and mechanics, just with better graphics and intro. As others have said, there are already two unavoidable NTR scenes in this small Demo/"First" Remake, making the claim false. Or the Dev thoughts are ->
'He's not with her YET, so EVERYTHING is allowed' lol. I stopped playing after the first scene. Surprised this game was revived after 2 years; maybe it should've stayed dead.
My opinion remains unchanged from years ago: the models, tiles, SFXs, music, and animation sprites are among the best for an RPG porngame. Good item diversity and combat system are its highlights, could have potentially placed this in my top 5 normally. The only other RPG porn game that tops it has its own unique trait and perk progression.
However, with the game heavily based on NTR and no changes made, I won't play further. It seems the dev thinks the FMC, presumably Amelia, will be unharmed, but not others since they aren't love interests. Based on what I've heard about the novel's events this game adapts, removing NTR isn't feasible as it's core to the fetish and plot, proving the cuck scenes are still unavoidable. Hope that helps.

You should check the pages here; webnovel readers have shared what to expect if not deleted by mods. But to save time;
Yes, a lot of NTR. Will they be avoidable? Only the creator knows. Since it follows the original plot, the answer seems to be no. Although it's a game with potential paths and choices, changing the story's core would require a talented writer, which the devs isnt't, and work on alternative paths. It's a cuck/NTR game where you play but fail relationships while getting cucked. The MC becomes aware eventually, but last time, 2 years ago, the story was at 65-70% completion and he was still clueless. We're talking about typical NTR scenarios where the MC, despite his OP isekai starter skill, remains oblivious while the FMC, his mom, and another girl have a foursome with a douche while he's fishing, thinking in the lines of: 'Hm, maybe something's off... Nah, I'm overthinking it! Time to fish!'
