Thanks for answering! Definitely going to check out the full game in the future.
I do enjoy cuck/NTR content (incoming wave of downvotes, as is the status quo for Itch), but I don't exactly like full GF-stealing, I prefer consensual cheating kinda stuff (and in fiction, non-consensual cheating, as long as it becomes consensual later). So, that type of content sounds great for me!
I've obviously not heard any proper lines yet, but if the few voice snippets in the demo were you, it sounds great! And also, excited to see those shopkeeper scenes! Maybe even an NTR scene with her..? Ah, but I won't ask for anything before I've bought the game!
