Social Anxiety Survival Horror. You’re a guy at a friend’s party trying to avoid conversations while putting in an appearance with your friend so they know you were here. You can deflect conversations with small talk you pick up by eavesdropping, but it won’t work on drunk people, so you also need to run and hide. Your ex-partner eventually shows up and is hunting you down to have a frank conversation about your relationship, which is instant game over.
I would disagree with that being a plot twist, though. You’re aware of both possibilities from very early on, and the idea that it’s real appears later than the idea that it’s not. It’s hard for it to be a twist when people keep directly telling you what the twist is going to be before it happens.
None. It’s not a good plot twist. Even the Truman Show didn’t use it as a plot twist, but as a premise. If the story was engaging without the twist, then it’s a gut punch to suddenly pull the rug and say “gotcha! The plot was meaningless!” If the story wasn’t engaging, then you didn’t get far enough to see the twist.
People come here because it’s big. It’s big because people come here.
What if we went over there? What if we made the one over there big? Big, and entirely under the control of actual fans of anime who don’t dismiss the entire medium as porn, I might add. Wouldn’t that be better?
