Jiang Nianwan, a horticulture girl whose life experience is a mystery, was abandoned in an orphanage since she was a child. A silver lock with the word "Nian" engraved on her neck is her only token. She was born with the constitution of a koi carp, always triggering small fortunes in desperate situations, and unexpectedly awakened the "Flower Language Space" - touching the plants can step into the glass greenhouse and talk to the flowers and plants. But she never thought that this ability would involve her in a fateful entanglement that spanned ten years.
Lu Shiyan, the aloof scholar of the Department of Finance and heir to the Lu Group, had a faded red string tied around his left wrist and had a photographic memory except for the girl's face. Until the day of the opening ceremony, the reckless Jiang Nianwan knocked over his meeting materials and the cherry blossom cookies were scattered all over the floor. He took her student ID card and said, "Tomorrow at six o'clock, we will pay off the debt in the conference room," which started the destined bond between the two.
