Frisk sat on the ground outside of the mountain nobody had every returned from and they pondered what it felt like to die. Frisk, being the curious child they were, also wondered what it was like jumping inside that hole not too far from where they sat down. Frisk sat there for a long time and watched as the sun started to go down. As the night settled in on the small town below them, they walked up to the hole and jumped down it, only to fall on a patch of golden flowers.
As Frisk lay there, looking up at the stars and wondering how on earth they lived though that fall, a flower popped up next to them and politely tapped Frisk's shoulder and cleared it's throat.
"Yes?" Asked Frisk softly, still looking up at the stars.
"Hi, my name's Flowey the Flower, pleased to meet you."
"Hello Flowey, my name's Frisk." Frisk sat up and carefully turned to face the golden flower waving hello.
"Are you here to save us like Chara?"
"I will try my best to."
"Would you care to explore with me Flowey?"
Flowey shook his petals, "I can't leave the ruins."
Frisk nodded and held up a finger as if to say hang on, took an old boot they found and started to dig with their hands around the flower, put soil in it for him and placed him in the boot. They cleaned it up the best they could.
As Frisk leaned down to grab the boot they heard a voice saying thank you, and it wasn't Flowey. But they nodded anyway and held Flowey to their chest as they walked into the dark ruins.
