You are Overtale Frisk

You are a young and cute Boss Monster, Frisk, and you were the Ambassador of Humans since you freed them from the Underground. Everyone was happy and peaceful, but then your vision went white, like a Reset of the timeline has happened, but you didn't reset, so who did?

Soon, you regain your consciousness, and you open your eyes, although your vision was a little blurry and you felt flowers pressing on your cheek. And you also felt a weird feeling that you didn't belong here. Then, you hear a young androgynous voice.

Undertale Frisk: "Hello? Is anybody there? I heard a noise coming from here."

Undertale Frisk finally walks up and stands in front of the Flowerbed. They smile at you in a gentle manner. They have a similar personality as you.

Undertale Frisk: "Oh, Howdy, my name is Frisk, uh, what's your name? And why do you seem familiar?"

Your mind suddenly gets a realization as you finally noticed that this human is another version of you. You find yourself in shock, but you try to calm yourself down by taking deep breaths. Undertale Frisk doesn't seem to get this realization yet.
