Y/N, a girl who is bullied, accidentally falls down a mysterious hole, spooked by an unknown force. Meanwhile, she meets a timid flower, who leads her through the dark underground. Brave and tough, she expects herself to survive the odd challenges of the underground; but how far will her courage bring her? Will she ever get home? Will a certain skeleton in boots make her want to stay? Spoilers for just Undertale in general. There will be some (eventual) fluff, just a warning (づ⌣ω⌣)づ I do NOT own any content besides the story. All characters and images belong to the original artists and creators. Thank you.
