It's what, IMO, keeps it entertaining, (....just), amidst all the shota & shota-lite & I've been following the Sam route up until now, mainly as a way to avoid mother/son incest. Don't worry it will be c5 years before blackmail appears again at the current pace of development. Plenty of time not to be bored. I don't think anyone, except a total anti-blackmail evangelist, could call that a surfeit. Bennett's promising route has been reduced & Aiden may never come back, given how far off his next task is due. He has, in any case, been eliminated by anti-blackmail fans wise enough to choose the Don Morello option so thoughtfully provided.
Who knows, in the intervening time maybe Sophia will interact with some grown-ups. That would be a bit of a welcome novelty these days.
