From the Hero to the Villain. [Dottore x F!Reader]

A once kind and youthful woman turned into a villain. The betrayals she went through, made her turn to the fatui. Once a heroic woman now a chaotic murderer known as The Apollyon. She hasn't felt this feeling known as love in many many years. She acts like these things don't interest her, but deep down, she wishes she could feel something like love again. Maybe one day someone will show her this feeling. The man she falls in love with is the one she hates with all her heart, but she has no idea that it is that man. Maybe there's a secret he's hiding from her.
