War amongst the humans and monsters has really messed things up for you. That is, until you meet a sexy skeleton. ((Note: this is a slow burn. You actually have the chance to fall in love instead of usual fanfic logic. Also reader is gender neutral))

u n d e r f e l l You were searching for your brother Frisk. He was obsessed with monsters, he always talked about being their friend. You never understood. He talked about Mt Ebott and how he wanted to climb up it. You had a sneaky feeling he had gone there. You packed your bags, heading out of town to only find the mountains core. A hole. You jump down... Was this the right thing to do?
