There's this Japanese video game that starts out as a cutesy dating-sim, but once you choose one of the lovers, the [[Yandere]](s) remembers your choices even if you start a new play through, and she plays with the Fourth Wall. What game is it?
Also, what's the trope when one playthrough affects subsequent playthroughs, à la Undertale?
