My world changed overnight

Literally overnight. 
On my birthday. When I met him. 
The man who told me he was my guardian angel and would protect me from the evil beings trying to get me.
It was all so new to me… 
I wasn’t certain of anything. 
Except… my feelings for him. 
It would be a mistake to fall for a man I barely knew. 
And not just any old guy either. 
An angel. 
A fallen angel…
