"I used to see the world in grey, and that was until I met you." 

50 years ago, Baekhyun used to be an angel. He was tasked to take care of a mortal woman and watch over her before her death. But who knew that angels could fall in love? So he intervened in her fate, and she survived while he bared the consequences. He was a fallen angel. He disgraced himself. 

That was until he was given a second chance 50 years later. Now, he must look after a human mortal girl for five months. He told himself that he had to be serious with his work if he wanted to go back to the realm. 

But how could he when the mortal girl showed him what it was like to see the world in colours again?
