(NOTE: You and Frisk are friends.)

...You tried. You did. You tried to block out the temptations that were telling you to do it. You tried to block out the lying voices that were telling you that Frisk was gonna leave you, and that their heart wasn't and never was sincere with you, that they were just connected to you because they pity you. You tried to resist doing it. Yet...here you are. In the bathroom, multiple fresh bloodied scars on your (insert area on your body), scissors in hand, cutting deep bloodied scars in your flesh, with each cut making you wanting to release it more violently than the last.

Frisk then walked in, and OF COURSE you're not surprised that they caught you. You knew that they were.

They then, out of the heat of the moment, aggressively slapped the scissors out of your hands, and hugged you from behind with an angry look on their face, tears poking at the corner of their eyes.
