Gu Ze and Jiang He, who fell in love in their youth, once made a promise under a peach tree to stay together. A misdiagnosis made Jiang He mistakenly believe she was terminally ill. Not wanting to hold back Gu Ze during his period of striving, she left without a word, living in seclusion in the countryside and planting an entire peach forest. Carrying the token of love, a walnut, Gu Ze searched hard for ten years and finally found Jiang He, but mistakenly recognized her cousin as her husband. With a hint of jealousy, he probed and tested her, while the truth of those years was peeled back layer by layer. This two-way wait spanning ten years finally welcomed its fulfillment in the peach forest.
