    Summary

    Oh wow what an original title--

    So most of these are gonna be copy-and-pasted over from my Wattpad account. This is gonna be my first time using AO3, so I'm kind of experimenting. The tagging system looks great though.

    Summary

    “you should be afraid,” he whispers, but you shake your head, refusing to be intimidated.

    “I’m not,” you say with as much confidence and courage as you can muster, attempting to reassure both him and yourself.

    Sans gently pushes you backward until you stumble into the nearby bed, laying down when he crawls up over you on hands and patellas, never once breaking his intense crimson gaze.

    “you will be.”

    ***

    Soulmates are a fairy tale, a myth, a legend that neither humans nor monsterfolks truly believe in. There's no way two strangers could unconditionally love one another, fall in love at first sight, stay together forever, no matter what. That's just a stupid fantasy...right?

    But what if it's all real?

    A journey about redemption, forgiveness, second chances, and discovering that your soul is eternally tied to another with a bond that transcends time and space...

    Yet your soulmate is someone far more broken than you.

    ***

    Summary

    Four AU’s have come to a happy ending on the surface. It is a new beginning for everyone, but Berry is haunted by his past that still clings to him and threatens to pull him back into the darkness, unknown to his now growing skeleton family. The newest skeletons are from the last set that surfaced: Fellswap. They are not going to let Berry be taken. Howl and Daemon, the two newest skeletons, have to dig into a horrible truth and show the world Berry’s past, and with the help of their fellow skeletons, they hope to make a better future for him and all other monsters.

    This is adapted from a role play with GetMcDunkedOn and me (Diyami). I hope you enjoy it.
