I might miss something. this is what I understood. the past was real, Rinne 's mother rape MC, death game , MC almost got kill by Kanae, Kanae promise to help MC, the bet between Nemu and Kanae. these was real until the beginning of the game. after that it was simulator. the simulator go until MC snapped Nemu neck. no way that MC snapped Nemu neck was real I mean neck snapped mean dead right? also the bet was to make MC kill Nemu in simulator. so yeah that not real. about the ending, I know the game not need to tell the player everything but that ending I felt it's abrupt like it cut short. when I played I just WHAT?? it's end??
