Angels are known as guardians to those in need. What most don't know is that angels are sent to this world in human form to fix fate that humans tend to step out of now and then. Ju Sun and Seo Joon happen to be two men doing just that. The two were once best friends and they are meant to be that way no matter what life they are in. One woman changed that all when they both fell for her. She could only like one but in the end her heart was too young to truly commit as she left them both behind for an opportunity in the states. Orders have been given to angel Min Jee to restore fate back to its rightful place for the two men. This is her one major mission and if she can accomplish it, she will receive her golden wings. It seems like a simple task to make the men make up and forgive one another but the havoc the two have caused on fate is going to prove to be a very tough job. Especially when the angel starts to cross the number one rule of heaven: never fall in love with a human.
