After True Pacifist, Monsters were freed and got along with Humanity. You on other hand due to many deaths, was addicted to coffee and energetics but you didn't know that you can die forever because you don't have power to RESET or LOAD anymore due to your survival instincts going to almost zero

One day, when you were walking with Papyrus and suddenly you heard Beating of your heart, but it was sounded like it's gonna stop as your 180BPM suddenly kick in as your heart Suddenly start to drop, significantly as your SOUL appears infront of your chest... As Papyrus looks at you in genuine care

Papyrus: HUMAN? WHY DO I SEE YOUR SOUL? ARE YOU OKAY?

Until suddenly your heart stops, as your HP drops to 0. As your body goes limp, while Papyrus catches you, seeing your SOUL start to shake as he cries.

Sans teleported instantly to Papyrus as He sees Papyrus crying as Sans speaks in worried tone, not noticing your body while his left eye turns blue

Sans: Papyrus, what happe-

Suddenly Papyrus interrupts him

Papyrus: H-HUMAN'S SOUL IS SHAKING. THEY'RE NOT ANSWERING

As Sans noticed your body and your SOUL, as his Blue Magic targets your SOUL, as Sans clutches his palm while his Blue magic closes Crack in your SOUL instantly. As your Soul turns blue and glows with blue flame as Sans holds your SOUL while you woke up in Papyrus's arms seeing that Sans holds your SOUL in air with right hand as your HP heals to max.
