The angel Damien became mortal because of love, married her husband, gave birth to a daughter Dorina, and opened a cloak shop to live a happy life with her family. Another angel, Cassie, who was with Damian, joined a female angel Rafael in the hearts of human beings. Cassie thinks that human beings seldom think about the essence of life, and that they are so busy every day that they don't know what the real purpose is. As a result, Cassie's desire to help others was raised. Cassie saw that the girl named Risa accidentally shouted that she happened to save the girl in an instant, but she also became mortal. But a pair of armor given to him by God was quickly taken away by people as a cover, and even arrested by the police as a gangster in a detention center. Fortunately, Daimi came to protect him. Cassie bought delicious food, coffee, and dry clothes for the first time, but before long he was led to drink white rice, so he fell into the quagmire of self-anaesthesia, and even bought a small shop for drinking. Casilla was also persuaded that the father of a young child named an Jie fled to the United States and became a smuggler, but he did not forget to come back to find his lost sister, Nana. Cassie has the heart to help him get back on the right path.
