You are an emotopath meaning you can feel emotions and a very strong one at that so felt more than emotions. Your parents were horrible to you and the students at school were no better. At the beginning and end of every day you would go to the tree, 'your' tree. Sitting in it not knowing someone else was there, and like the song goes you might end up k-i-s-s-i-n-g.

It's been a few years since the monsters had been freed from the underground. You can't say you hated it, though. Sans had been one of the first monsters you befriended (only because of his sexual puns,) and he had introduced you to his group of friends. One of his friends, Grillby, caught your eyes. You had started seeing him more, and you even started dating! Sans supported this and was supportive of your decision to date his friend. But, even after going through tough times, Sans had your back, and helping you through thick and thin. And you trusted him, he was your friend! But in Sans' view, you were more than a friend.

She loved to sing and dance and rhyme. But her happiness was running out of time. She screamed and clawed to anyone at all, Because blood and skin couldn't break her fall. Tears and sobs and screams ran out, And still nobody heard her shout. Humans, monsters, but nobody came. And to everyone else they did the same. She was lucky he was being kind that day, So he didn't take her life today. Smiling and happy, her journey began, To free all monsters was her plan. She wasn't perfect, But it was worth it. She didn't want to be best. But despite everything, she never reset. (Horrortale!Sans X Reader)
