Nah i agree with the other poster, i love the avn but some choices esp in the early parts are simply stupid. The pencil being one of the more obvious ones but losing dalia's part for not being a pervert is rather lame tooHonestly I wouldn't call it inevitable at all. You might miss a path or two going blind but most of the choices are pretty easy. Just don't be a dick.
And lets be honest, even taking all the good choices or esp if you take all the good choices (with all girls), its the uber dickmove, we can just be glad that were in a harem avn and the girls magically dont mind the mc being a cheating sumbag as long as its "between the group"
but man, orion would be the worst kind of sick heartbreaker in the real world
Imo the choices get more logical in the later chapters (like the annie date) but in the early parts its quite stupid (but funny) at times lol
