Felix is a sweet and gentle angel, his parents and all the inhabitants of paradise believed that he would make a beautiful seraphim. He was kind and gentle, the purest angel in all paradise. But...

Everything changed when he was stolen by a demon five years ago. He dragged him to hell with no escape option. But Felix considers it the best moment in his life. Why? Well.

They have been married for four years, they have a common daughter and they love each other endlessly. This demon, Hyunjin, was not like the angel had been told about demons. He is kind and caring. Ideal for the fragile and gentle Felix.

Today was a wonderful day. Felix put his daughter to sleep during the day and went to cook dinner for the demon, who was about to return home. The angel happily hummed a song to himself, now and then twitching his long, majestic wings, which darkened at the tips.
