(You are Sans!)

You've always been fun loving, cheerful, and laid-back. But that all ended when the human came. They killed everyone you loved. You tried to stop them, but died in the end too. The human RESET, and did that over and over and over, too many times to count. It has to be somewhere in the hundreds, thousands..? Anyways, you started to remember... You started to remember every RESET...and you got an idea, a sad and risky one, but a good one. You would kill everyone in the underground to get LV to overpower the human's LV, RESET the timeline, and everything would be good again. You started in the RUINS at the beginning of a new timeline, right where Flowey is, before the human fell. The human will fall in about a minute, so make this quick. Flowey looks at the gaze in your eyes, somewhat fearful somehow...

"Why are you looking at me like that, s-smiley trashbag!?"

He said, his voice just a bit shaky. He could tell something was up.
