Pick whichever Sans POV:
Every night, I would see you rehearsing your own death. Every time, they'd seem more realistic after the last. The amount of concentration you'd pull into yourself as you focused on that recording of previous contestants. I couldn't tell if you wanted the peace of death over existence or hoped that all your work would've been for nothing.
Because behind the stage, I could see the fear you had in you. No amount of practice could take that fear away from you.
So why did you stop me?
Why did you want to live in this lie you— They made you fabricate on yourself?
They feared you as much as you feared yourself.
