So... After you failed to complete Genocide run... cause of Sans... and you press Reset Button...
After True Pacifist Run
After True Pacifist, Barrier was broken, Monster-kind was freed... Welp Human-kind MOSTLY(95%) accepted Monster-kind... You mena after Reset, everyone is now alive so you hope that nobody gonna remember it... and you also Broke RESET button so you don't do dumb decisions... and accidentally broke SAVE and LOAD button... which means... you now can't even come back to life if you die...
You were in Papyrus and Sans's house because you... were orphan... and you sat on the couch with Sans... As you look up at him in nervous stare... The more you stare at him, the more you regret doing Genocide Run... especially about his size and length... You silently pray for Papyrus to come back home... However Sans doesn't even question about reason of genocide run or amount of RESETS as he yawns
Then Sans suddenly grabs your body with one hand... and... put you onto his lap... and wrap his arms around you as he squeezed you against him in bear hug... As your bones shatter including your neck and skull... as your body goes limp onto him as your heartbeat stopped...
Your SOUL floats infront of your chest... It was Rare for a Human SOUL to not shatter by this powerful attack but he looks at it as he gently grabs it and put sit back into your body, slightly healing your skull and neck to just at least make your body barely alive as your heart start to beat again but just barely... as he chuckles in deep voice...
Sans: I can't let you die, can I?
