First, go learn the difference between other games and this one before saying F or whatever to others for wanting a good outcome for a game without giving some random BS about reality!
Those other games become a mess when you have to add a lot of stuff in order to give everyone what they want. This game is about choices and having a route of both Sayuri & Asami wouldn't ruin the game!
Of course you'll find absolute random & irrelevant arguments to defend your take giving how are hell bent on talking Sh*8 about people who actually want a good outcome! But Okay, have at it at your own fantasy!
The thing is, more than half of the people want a route for Asami & Sayuri, you can cry about it saying that "They shouldn't be given everything," but there's something known as "Player Feedback." Now, that might be a new term to you, but world is a big place.
Go find out instead of being salty that people don't agree with your take!
