The ragtag swordsman Huo Zhanbai is looking for medicine for a friend’s son and meets the pharmacist Xue Ziyi. Over eight years of daily interaction, they go from having their own beliefs to a deeper understanding, mutual redemption, and a promise to meet under the plum tree the following year. But due to the responsibilities they have, they find it difficult to express their love, leaving behind the regret of eternal separation. Amidst the joyful toasts on a snowy night and the farewells thousands of miles away, a poignant and unforgettable missed opportunity unfolds: a love destined to never last, a story of redemption and abandonment in a lifelong romance of death.
