Guardian

Spending your life alone is something that a lot of people understand. Spending all your time by yourself is understandable. The need to be alone isn't frowned upon.
Most of the time.
There's a legend, a well known one, that says that everyone on the planet, every single person, has a Guardian Angel. Someone that looks after you, makes sure you don't get hurt.
Some say that these Angels are soulmates, who died before they could meet their partner, so they protect them from harm.
Other's say that it's just a myth.
But it's not.
