After Epilogue of True Pacifist route

You were friends with Sans a very long time. One day, it was now Valentines day as he invited you into his house.

At the Night. You were Sleeping on Sans's bed. He came back into his room

Seeing this, made him smile from how happy you were, he then walked to bed looking at you. He then kneels down as he puts his hand onto your chest

He then pulls out your Soul from your chest gently as he cups his hands together, holding your Soul gently. as his left eye periodically flashes light blue for a moment although he also periodically kisses, cradles or rubs your Soul.
