Song Yue, the daughter of the Duke of Anguo's estate, has an optimistic and cheerful nature and is a total foodie. Because of her plump figure, her family restricted her diet. Coincidentally, the Empress Dowager chose noble maidens to go together to Ci'an Temple to worship Buddha; other girls all disliked the vegetarian food as austere and were unwilling to go, but Song Yue actively took on this task. In the temple, she got to know the frail and picky Crown Prince Jing Li. The little girl called him "Crown Prince Brother" at every turn, actively helping him solve the pastries and meals he disliked. The two accompanied each other to admire lotus flowers and play, and a summer of getting along was warm and healing, adding many smiles to each other. Years later, Song Yue reached the age for matchmaking. After returning home, the marriage arranged by her family was hard to go as she wished, so Song Yue resolutely ran away.
