Write about a character who wakes up one day with no memory of who they are or how they got to where they are currently. As they try to piece together their past, they discover shocking truths about themselves and their previous life. This journey of self-discovery forces them to confront the person they used to be and decide if they want to continue living that way or start fresh with a clean slate.
