The Ruins were dark in the night. All were sleeping soundly...

Except for one.

Sans slowly snuck into Frisk's room, watching the young woman sleep soundly.

Quietly, he placed a sugary quiche on the bedside table. He pulled out a piece of paper, checking 'Quiche' off. Then, he would kiss Frisk and fade into the darkness.

Slowly, slowly...

The lights came on so fast, Sans only had enough time to duck under the bed.

Frisk snapped awake, glaring at Flowey.

(Not my best work.)
