Forgetful Flowers

Frisk has been underground for over ten years now, and she's made more friends than she ever had before. However... she meets someone else that changes a lot for her. Each night, they come to her, seize her body, and make her do unspeakable things. She can't tell anybody about it though, for fear that they'll hate her instead of try to help her. The King falls ill because of her, but doesn't have the memory of what happened. But she knows that if she goes to visit him, he'll remember, and all will become true. She has to find a way to tell everyone herself before the truth gets out, but the clock is ticking.
