He is Su Ye, a mysterious man who has awakened from a thousand-year slumber, and the last "dream keeper" in the world. His power comes from protecting the pure dreams of the world, weaving hope and resisting nothingness.
She is Lin Wanying, a dazzling top actress, known as the "Midnight Firefly". In the glitzy entertainment industry, she always protects the pure and biggest secret in her heart - her daughter, Nian Nian.
Five years ago, an unexpected encounter happened like a dream. Five years later, Su Ye woke up in a hospital bed in a modern city. The first thing he saw was a pretty little girl who timidly called him "Dad."
When the last dream keeper becomes a new baby daddy; when the bright starlight shines into the ancient inheritance. Su Ye discovered that his daughter's wild dreams were actually his most powerful source of strength. She dreamed of a candy house, and he could turn stones into candy; she dreamed of a starry sky dragon, and he could summon starlight as armor.
However, in the shadows of the bustling city, there are not only flashbulbs and paparazzi, but also "dream eaters" who feed on nightmares and erode people's hearts. In order to protect his most precious "dream", Su Ye had to regain his ancient power and walk between the stars and the night as a nanny, becoming the most solid support for his daughter and her mother.
This is a story about protection, healing and love. Let's see how a thousand-year-old dreamkeeper brings up children, pursues his wife, and... Saves the world in a modern city.
