[An AU where Chara never wanted to be a villain.]

Undertale, or the 'Underground' as the others call it, has a reputation for it's monsters. When one day, a human named Frisk falls into the underground, greeted by Sans and Papyrus. She has a violent Alter Ego named Chara, whom no one knows of, who chooses violence over peace.

But in this AU, Chara never wanted to kill others, she didn't have a choice. Frisk made Chara violent to protect herself, Chara never wanted to kill, she did it for protection.

One day, as Chara is fighting Undyne, she suddenly stops. She doesn't want to kill Undyne, she's too guilt to kill her.
