It's a terrible day outside.
Birds are fleeing,
Flowers are wilting.

And you just came here...
Will you change us or become one of us?

Welcome, Frisk.
Have a horrific time...

"Psst! Wake up, human, quickly!"

Frisk, still confused by their fall, looked up to see a golden flower with a fearful face. They looked questioningly a the flower, wondering whether to trust it or not.
"Hurry up! We haven't got all day! Toriel will be coming soon and that will be the end!" The scared hissing from the flower came again.
'That will be the end!' They supposed that was a good enough reason to join the flower. Frisk slowly got up, face scrunching up in pain. Quickly dusting off their blue jacket and purple shirt, Frisk stared at this flower for help.
"Alright, follow me!" The golden flower seemed to disappear underground and appear in a brand new spot not far off. Frisk, although still confused, followed the magic flower.
Passing through gates, the pair dodged the sight of monsters and stuck to the shadows. The underground didn't seem all that different from above. Grass and rocks, the ruins of certain places were a change of scenery, though. Frog looking creatures, odd flying moth-ghosts, and carrots seemed to be crawling all around. Later Frisk would learn them as Froggits, Whimsums and Vegetoids, but for now there was no point in learning.
Eventually, the golden flower stopped at a dark, empty room. Eyes darting from side to side, the flower looked hesitant to say something.
"Alright, uhm. Let's make our introductions quick. I'm Flowey, Flowey the Flower," Flowey gave an anxious smile and tilted his petals waiting for Frisk to speak their name.
"I-I'm Frisk," Their voice was quavery and quiet, they definitely didn't speak often.
Flowey nodded a couple times, golden petals bouncing up and down.

"Great! Alright, Frisk. I don't know how you do things up on the surface anymore, but here? Things are a lot different-emphasis of 'a lot'. Everybody here, well... They're all cruel and mean. Liars, cheaters, murderers, thieves. Now you're probably wondering, 'Why should I trust you then?' Well, you'll just have to hope I'm not lying, after all, there's even a little good in this world. Anyways, I've been waiting. Waiting for someone to help me, that's a story for another time. The other seven humans that came here, they were bad. They all acted like the monsters here, and each one died because they were stupid, weak, driven by madness or all three. But you. I think there's good in you. There's some weird vibe I get, like the feeling of hope. You've gotta help me. And not only me, but yourself too. Maybe we can both find our way to free ourselves of this prison."

But Frisk shook their head, brown hair smoothly following the movement.
"What do you mean, 'no'? If you think we can save everyone here, it's too late. They've been corrupted for centuries, think about why they're all here in the first place!" Flowey's scared voice started to raise from a hushed whisper.

Frisk's face looked stubborn, and they crossed their arms.
'I'm going to save them all.' Is what they seemed to mean. They were definitely determined and nothing was going to change their mind.

"B-but," Flowey faltered, but he gathered himself up and seemed much taller than before. "You know what? You're right. We should save them. Save them all, every last one. I'll help you, Frisk. No matter what."

Frisk smiled and gently hugged Flowey, making sure not to harm the delicate flower. And for a second, tears seemed to sprout out of his eyes. The one hope that could change all of the underground was right here, and he was going to help them.

"Then let's go. Toriel will be busy in her home for quite a while. Our time to help everyone in the Ruins is now."

Frisk smiled, and the pair headed out of their secret ground. When they were almost upon their first monster though, Frisk stopped. Flowey looked questioningly at Frisk, and dragged himself to the human. Frisk dug something out of the ground, making their fingers grimy with dirt, but they didn't mind. It was an object made of brown clay, like a cylinder that started thin at the bottom and then widened up. It was a flower pot. The human pushed the flower pot to Flowey, a gesture to ask for permission.
"But, why?" Flowey looked at the flower pot and then at Frisk in a disgusted manner.
Frisk grabbed the pot again and hugged it, "Together."

Flowey nodded his understanding and waited for Frisk to dig him out of the ground and place him in the pot. Not afraid to get their hands dirty again, Frisk plunged their hands into the ground and made sure to cover the inside of the pot in dirt first before placing Flowey in. Once inside, Flowey wiggled a little, making himself comfortable and then smiled.
"Let's go."

Their first target was a Froggit, and it showed no mercy in it's attacks. Frisk was still a nimble child though, and they wereable to dodge all but one of the attacks, even with Flowey in possession. Slowly but surely, Frisk and Flowey showed the Froggit kindness. Eventually, it gave in. They accepted the spare. One monster down, who knew how many to go?

And not so far away, there was someone humming a tune. The Froggit they had saved was now trembling in fear, but did not move to run away. Flowey also seemed oddly quiet. Maybe the hummer wasn't going to stay inside for the day.
