Old Notes Are Silent

In 1999, Xu Yuan wrote her secret love with an "X" and stuffed it into the mailbox at the school gate without affixing a stamp. In 2015, during the snow mountain training camp, she met that name again - Zou Fei. In the glacier crevice, he held her wrist for two seconds, and the temperature in his palm became her only evidence of resisting the cold winter in the next ten years. In 2022, Zou Fei's heart stopped forever at the depth of the 5,620-meter avalanche; while in the chest of another girl, his heartbeat restarted. In 2025, the old letter returned and the recipient code-named "X" appeared. Xu Yuan took the postmark of 1999 and rushed to the snowy mountains to complete the last delivery. In 2035, the "Unspoken Post Office" is hung at the door of the used bookstore - all letters that are too late to be sent will be answered here. Spanning 36 years, four cities, three sunrises, and two hearts. This is a long and affectionate confession about "missing and perfection, life and death and inheritance": That love you never heard, I will spend my whole life delivering it to you.
