Are you capable of understanding there's a difference between these two things?
What I said, as I've consistently said, is that not allowing for there to be an endgame relationship for the main pursuable love/romantic interests is a failure in game design since adult VNs and games are generally predicated on the principle that you can pursue and end up with the main relationship of your choosing. There will always be players who want to end the game with one of these primary relationships and there should always be a path to achieving it, but allowing the player to be in a relationship with their chosen LI(s) for most of the game but not at the end is, in my view, a failure of game design.
If, however, the MC faces an unavoidable choice of who to give his inheritance to, this would be perfectly in-line with his character because, as I also said, he is a selfless person who puts others before himself and who doesn't put much stock in having great wealth. So if such a moment were to arise, it would be completely on brand for him to want to at least offer this money to one of them because he knows it means more to them than to him. If a player doesn't want to give either of them the money, well then they just don't understand the MC very well.
