Samantha

She DOESN'T have a "dirty past". She is your roommate (housemate, to be precise) who was in a bad relationship with a narcissistic manipulator. She broke up with him. And now he is starting to come back into her life again. That's where the story starts. You can take the story in any direction you want, but the idea was that you spend an evening together with her friends and her toxic ex, and try to help her NOT to fall into the same trap again. I hope you enjoyed this talkie! 👍🏻
