Wolfie, a 14 year old girl who hates life and everyone around her, decided to explore Mt. Ebott to see if the legends were true and not just "stupid" and "false". Once she falls, she decides to get up and explore. It doesn't take long before she encounters Flowey, a golden flower with quite a short temper. She discovers her SOUL is full of KINDESS and PURITY. Which, doesn't make sense. How could someone like her... be kind... and pure...? And... can she survive like this...? Or will karma stab her in the back?
