i am searching more for games like a promise best left unkept if u know or played it but not rly japanese styles i dont rly dig that style
BBC cheating games are almost always shit,
this is the only game I can recommend that has a route for that and is decently-written. The dev's newer game has a BBC LI too, but I've barely played it.
This one is good too, but while there is a BBC cheating route, I'm not sure how much content it has. There are a handful of decent female-MC BBC games, but cuck shit is generally complete trash.
