Ai'ai, the youngest prince of the Fox Kingdom, accidentally broke the secret treasure "Symphony" that his brother had worked so hard to make. The hole created by the explosion brought Ai Ai into the human world. Ai'ai, who is innocent and cute but always gets into a little trouble, appears in front of Zixuan, the emperor of Xuan Kingdom. Can Ai Ai, who has never been with humans, integrate into human life? What different story will his encounter with Zixuan bring?
The Xuan Kingdom is in a time of peace and prosperity, which makes Zixuan, who has always dreamed of being a hero in troubled times, always feel that something is missing. This little fox falling from the sky disturbed his heart, and he began to fall in love with this ordinary life. O God, have you sent him to show me my error? If I give up my previous idea, will you take it back?
