Modern office worker Lin Wan is in a car accident. When she opens her eyes, she has become the companion spirit plant of Xiao Jue, a prince of the Dayin dynasty. Trapped in a flowerpot, she can only stay alive by drawing on his spiritual energy. When danger strikes in a secret chamber, she uses what little consciousness remains to control the grass and protect him. By a spirit spring on Blackwind Ridge, Xiao Jue helps her take human form through their companion bond. As their consciousnesses mingle, they glimpse the feelings each has kept hidden.
After taking human form, Lin Wan not only gains the ability to control plants, but also forms a “Heartbond Pact” with Xiao Jue, sharing spiritual energy and resonating with each other’s emotions. Together, they eliminate the remnants of Xiao Yan’s faction: she tracks rebels with her vines, while he uses political skill to stabilize the court. Their days in the Eastern Palace bring sweet pranks in the study, cozy moments planting flowers in the courtyard, and the joy of welcoming a new life.
From a spirit plant on a flower stand to a companion consort standing beside the emperor, Lin Wan uses the spirit of the plants to keep him safe, while Xiao Jue vows to protect her with the realm itself. At last, they ascend the throne together, with flower and leaf sharing the court. Their bond, born of spiritual energy and sealed by true love, becomes a story of perfect devotion across the lands of Dayin.
