Joker x Reader: Hostage Situation
A complicated and possibly corrupt romance(?) story about you and the Joker from Suicide Squad (2016). No spoilers, set before the timeline in the movie. Character representing you is gender neutral, so any gender (male, female and others) may read and enjoy.
Mature themes may come up later on in the story, not confirmed but it is a possibility.
Without giving too much away, I hope you enjoy!
