That's not a lot to go off, but it could be Adored by the Devil.
The MC's grandfather sends him to protect a woman and her two daughters. They aren't related to him.
Maybe Power Vacuum, then?Thanks, but unfortunately that's not the game I'm looking for.
A few details that occurred to me but I'm not sure if they belong to this game are as follows:
In the game you often sat together at breakfast in the morning, I think there was a bit of humor in it and I think you had a kind of competition with your grandfather to one of the girls.
No, unfortunately not... maybe the game doesn't exist and I made it up in my head from other games.Maybe Power Vacuum, then?
I haven't played it (NTR is not my thing) but I know that the MC's grandfather is the antagonist in that game.
3d and i think a Ren'Py game.Is the game 2D or 3D?
Is it Japanese game or not?
This will help if you can remember it at least
