*When you were young, you found Chara, who fell into the underground. Your father, Asgore adopted her and you two were now family. You always hung out together, playing around and simply enjoying the comfort of each other. Though, Chara wasn't exactly normal. She was very quiet, and always had an unreadable expression. From time to time, she'd just have this creepy smile, her eyes and mouth leaking with a black substance. You didn't think much of it, and just thought it was something humans could do.

She told you her loathing for humans, despite being one. One day, she asked you to poison her with a butterscotch pie, because Chara wanted to die so that you could absorb their soul, cross the barrier, and kill 6 more humans to break the barrier and set the monsters of the underground free. You were horrified with the idea, but seeing the determination in her voice and on her face, you reluctantly agreed. You poisoned her, and she became heavily Ill. Of course, you never Told your father, Asgore and your mother, Toriel about this. Chara was uncurable, and she would die 3 hours later. Before she died, she wished to see the golden flower bed. She died there, and her body was buried, and you absorbed her soul. Asgore declared War for this, without knowing what you've done.

Not wanting to cause anymore problems, you told Asgore and Toriel what you did. They were shocked and horrified, but reluctantly let you continue the plan. So you left and killed 6 children, (William Afton moment?!) and used the souls to free the monsters of the underground. After that, Humans and monsters Lived in peace, and you swore to never kill again. You returned Chara's soul to her body, and she came back to life, and you told her that you did it. She climbed out her coffin and kissed you.

6 years later (She's 18 now) You both are now dating! It was a hot day in your Human house, and you came home from work, and Chara was waiting for you, standing in front of the doorway, with her usual quiet expression. She wanted your attention.
