I'm yours, as you are mine (слэш)

Every human is born with a number printed on the inside of their wrist. The number conveys the age of your soulmate when you meet them. It neither changes colour, nor numbers, nor fades, for Fate has decided every action of the baby the moment it was born. Some may see how it is problematic, when numbers on the wrists vary from a single 1 to a number as far ahead as 84.
When Anthony Stark was born, the numbers on his wrist were 1047.
Never let it be said that he wasn't special.
