When archaeology graduate Su Wan sorts out letters from a Song Dynasty tomb, she’s shocked to find details like “jade buckle on the lapel” and “poem inscribed between pines”—they mirror her breakup with Chen Mo, a relic restorer, three years prior. She ended things over a misunderstanding about his “infidelity” but never sent the letter explaining the truth. Now Chen Mo returns as a restoration expert for the project. As they reunite, the tragic truth of the Song lovers—who regretted their whole lives because a final letter never arrived—comes to light. Will they repeat the ancients’ regret of “the letter left un_sent,” or face their hearts and untangle the “unsent letter” from years ago?
