I suspect whenever the split happens, Sakai will move onto something else and, even if it's like, camgirls or whatever, I bet he'll still be happier because he's getting *something* back from it, even if it's just fake kindness and gratitude, which Phil can't even muster up. Even then, this might be more of a "what could have been" with time as opposed to the spent money specifically, but I feel like they're kinda linked. But in the end, instead of growing, I think they'll just move onto some other parasocial interaction. It's basically like how Phil went from one gacha game to playing Champions.
