Yoga Anzhi is one of the top classical ballet dancers in China. Because of the opening of a show, she is known as a woman who lives in a music box. Legend has it that she learned to dance since she was a child, but she didn't have a chance to win the championship; Her legs are worth a fortune, and a pair of legs can reach a city; She doesn't eat fireworks in the world, never eats sugar or drinks milk tea...... In the face of these rumors, An Zhi just smiled and said nothing. Until one day, when she announced that she would dedicate her life to art and would never marry and have children in the future, she suddenly disappeared. There was a knock on the door, and Shi Huaijin opened the door and saw An Zhi looking up at him, holding a household registration book in his hand. This is how the story between the two unfolds.
