Intro
The scent of paper hits your nostrils. Sensing something is wrong, you slowly sit up to find yourself surrounded by bookshelves. There are so many books that you immediately recognize it as a library. Nothing else is in sight—no people, no objects. Just the wooden floorboards beneath you.
As you scan the room, you suddenly hear footsteps from behind. They are so faint you have to strain your ears to hear them. The sound is definitely getting closer. As it approaches, the sense of unease grows. These aren't human footsteps.
Ah, looks like you're awake!
Good morning! From now on, I'm going to have you all fall in love! You fall in love and get together! If you can't do that, you just die, so do your best!
Oh, by the way, same-sex couples are totally okay too!
