Stuck in My Sister's Dating Sim

My sole intention was to preserve my sister’s game, but how did I end up becoming a part of it? I suddenly found myself transported into my younger sister’s foolish dating simulator game! Despite my prior experience with the game, it became apparent that I had been reincarnated as a troublesome, inconsequential villain who dies too soon. My priority now is to live quietly and devise a way to return to my own world, but things aren’t going according to plan. Can I manage to escape from my sister’s dating simulator game?
