Soulmate AU where everyone wears a mask, and they can only take off their mask when they find their soulmate: the person with the mask identical to their own.
Elaboration: When a child turns 10, their mask appears, and they must put it on at all times. It will not be able to be taken off until they meet their soulmate, and it will grow along with their face; they'll never outgrow it.
EXAMPLE SHORT STORY:
