Taiki Kirioka meets an angel named Yun on a night near Christmas. Yun has been tasked with making Taiki happy as part of a test to become a full-fledged angel. Her best friend and fellow angel, Hinamina, observes that Yun is starting to admire humans and even wishes to become one herself.
As Yun grows closer to Taiki, her feelings deepen, but the path to completing her mission is complicated by her own desires and the rules of the angelic world. Hinamina's concern for Yun's changing nature adds tension, forcing Yun to choose between her duty and her newfound emotions.
