Doki Doki Literature Club Plus! (US)

After a period of silence, she will start to cycle through dialogs on various random topics. You will have to listen to 15 of these fully. They scroll slowly, and there are more long periods of silence between each dialog (~15-20 seconds).

In the settings, set the "Auto-Forward Time" all the way to the left, and turn on the "Auto" text button. You can leave the game alone and it will progress on its own. I'm unsure exactly how long this will take, but I think it should be 20 minutes or so.
