I Never Meant

I never meant to fall in love. I never meant to have children. I never meant to become involved in a war. I never meant to lose people I love. I never meant to let us be thrown down here. I never meant to become the royal scientist. I never meant to do lots of things in life. But I always meant to live.

Undertale- Reset

"Promise me one thing- just one thing only." Frisk nodded vigorously. "No one can know about this whole reset thing. Not Papyrus, not Asgore, not anyone.

Corruption (OLD)

You died. Again. But, when you woke up... You were back at the beginning. You didn't reset... but something was off. Flowey seemed skittish, frightened even. He was KIND.
