Summary
Frisk has faced danger and death many more times than any child should ever have to, but they aren't out of the woods yet. Being the first human in who-knows-how-long able to use magic has shoved them back in the spotlight. And just when their life was settling down into whatever counts as "normal" for the town of Ebott's Wake, where monsters sell ice cream and the gym teacher thinks anime is real.
It's nothing they haven't had to deal with before at this point, but that doesn't mean it's going to be easy, even with Papyrus taking over as Ambassador and the Finest scientific minds in the town working on a way to help Chara. After all, the first fallen human climbed Mt. Ebott for a reason, and it wasn't a very happy one.
And now, that reason knows about Chara too.Series

Summary
My version of Flowerfell. Frisk, Chara, and Flowey are the main focus because I think this friendship has a (skele) ton of potential that's sometimes overlooked.
I will not be shipping Frisk, Chara, or Flowey with anybody, including each other. In this story, Frisk is seven, Chara is thirteen, and Asriel/Flowey is twelve. I will include a few scenes of Sans x Grillby, and I may include Papyrus x Mettaton, but I'm not sure.
There will be angst, and a closer look at how Frisk's health would be affected by buttercups growing out of their skin. If you don't know what that would entail, please do research before reading. Saying that it isn't pretty would be an understatement.
There will be fluff and fun and shenanigans, it isn't JUST angst.
Edit: I decided to add in an original character. Boom. -

Summary
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.
