All Guardian angels are born with a Chosen human. When this child is born, the angel comes into being to protect and care for them during their life on Earth. For John Watson, all he cares about in the world revolves around his Chosen, Sherlock Holmes. Watching him grow up though, the angel soon learns that God must have had a sense of humor the day he decided to make Sherlock, as trouble seems to follow him like a magnet wherever he goes. John can't decide what's worse, the idea of losing his Chosen one, or the fact that he may be breaking the most taboo law of heaven as he disguises himself as a human to better protect and befriend the beloved detective he's always watched from afar.

He was meant to care for him.

But what happens when caring evolves into something more?

What happens when an emotion an angel is supposed to be incapable of possessing comes to life suddenly and viciously inside John's chest ?
