She is the daughter of a tea merchant in Canglan. Her family fell into ruin when she was eight years old. She followed her mother to live in the tea mountains of Motan, where she relied on her hands and an ancestral handbook to reestablish her roots.
He is the only son of a wealthy businessman in Motan. Before he was a wealthy and delicate young master, he was living alone in the shadow of his father's domestic violence.
When he was six years old, he met her, who was sunny and cheerful. From then on, she was the only light that shone into his life.
The times are turbulent, the tea industry rises and falls, and they experience separation, reunion, hunger, and catastrophe. She secretly hid a handful of tea seeds for him during the most difficult years; he struggled alone in the darkest night, approaching her step by step.
A whirl of tea fragrance, from Canglan to Motan, and then to the tea gardens all over the mountains and plains of Yanzhou.
A lifelong obsession, from the bandaging at the age of six to the reunion on the mountain top eighteen years later.
"Look at this tea tree, it looks dead in winter, but when spring comes, it comes alive again."
"It's the same with people."
She is his only spring, and he is her eternal heartbeat.
This is a story about the fall and rebirth of the female protagonist, and the redemption of the male protagonist from "a boy in the abyss" to "illuminated by a beam of light". The two people's encounter, separation, reunion, and stay together are closely intertwined with the rise and fall of tea culture.
