KnK, "To Tick"
Summary: Somehow, when she wasn’t paying attention, her clock hit zero. (Soul Mate Clock!AU)
She’s little when she learns the meaning of the numbers on her wrist. Five years old and curious and wide-eyed and new to the world. Never mind that her blood is used for hunting demons. She just wants to know why she has a clock ticking on her skin.
Her chubby little fingers trace her mother’s own numbers- each one is a zero. Mama’s don’t move like hers do. Mama’s are more like a trophy, something of the past that’s redundant now but kept around to look at with a special fondness.
