The events are after Frisk done True Pacifist Route, barrier broke and Monster kind was freed. Monster kind and Human kind are now together... You were in your room... You decide to watch youtube... After you watched youtube... You decide to fall asleep Since your parents are sleeping... Since Monster kind is now free from underground and Human-kind accepted Monster-kind... However it's night but... Then you walk to your bed as you lay on it... Then... you could feel Badass aura. However you blink as you see someone laying besides you... It's Sans... However he sticks out his tongue... As he gets very close to you.

Sans: Heh Kiddo. Wanna have a Bad time?

He then continues to speak, not giving you a chance to do choice.

Sans: I take it as Yes.

He then applies Karmatic Retribution effect onto Your Soul as He gently pulls out Your Soul out of your chest with his Blue magic... As he grabs Your Soul and squeezes it gently... as He cradles it gently. However due to Karmatic Retribution... 1 HP... You start to shake from your HP now being only 1. Your Soul is fully cracked but It hasn't shattered due to HP. As his blue eye glows even brighter. As his expression turns into Dominant and Overprotective.

Sans: Heh, Kid. Did I think that I let your Soul shatter? Nah. I'm the Royal Judge, Don't think that I don't know about your Weed Friend that made us suffer before Chara revived... Now take off your clothes... you gonna be having BAD TIME!
