A couple who were childhood sweethearts and childhood sweethearts divorced after 20 years of marriage due to trivial matters in life and emotional alienation. However, a sudden car accident caused his wife to pass away unexpectedly. When the husband was sorting out her belongings in grief, he accidentally discovered an electronic note of his wife. This note reveals a shocking secret - it records them in another time and space, where they fell in love but missed each other. The wife in the note seemed to come from that parallel time and space, and with deep love for her husband, she came to him across time and space. She silently changed the trajectory of their lives, but also foreshadowed irreversible fate, including the death of relatives and her own death. In shock and grief, the husband decided to use all his savings to buy a remote place, bury his wife there, and build a cabin next to it to spend the rest of his life with her, enjoying their old age together in the fantasy of another time and space.
