You know those Truth or Dare and Never Have I Ever games that never really work as IC games, because the characters tend to be too nice/polite to ask really embarrassing stuff?
Say they're forced on the characters by the world, and the characters aren't even allowed to choose the truths/dares/questions themselves, but the world chooses them?
Basically it'd be The Mistletoe Event 0.2: two characters are forced to play one of the games (otherwise they can't leave the spot?), but it's the world (ie, us or an RNG) that decides what questions they need to answer. It could be questions all about love/sex/relationships, to fit the Valentine Day theme.
