2026, Ningbo Laowaitan. Documentary director Shen Shuyi and badminton legend An Shiying reunited after 17 years apart. Between their gazes lies a forgotten summer, more than six thousand promises burned on Wednesday afternoon, and a jar of ashes called waiting.
In 2009, 16-year-old Shen Shuyi met 15-year-old An Shiying at Gwangju Sports School in South Korea. The two girls warmed each other in sweat and made a vow at sunset: one would become a world champion, and the other promised to record it with the camera. However, an accident on the eve of departure caused Shen Shuyi's head injury and her memory was completely reset - she forgot Korea and An Shiying.
An Shiying, who stayed where he was, began a long wait. She reached the pinnacle of the badminton world with amazing willpower and became an Olympic champion. However, she went to the abandoned "white building" every Wednesday, wrote letters that she would never send, and burned them. Ashes filled the glass bottle, measuring the years without any response.
In 2026, Shen Shuyi returned to South Korea for work. A series of unexplained clues - dreams, old photos, a "white building" that matches reality - lead her to An Shiying. When the amnesiac follows the fragments to pursue the truth, and when the waiter finally waits for those eyes to look again, the broken time begins to be stitched together by love.
From the banks of the Yongjiang River to Wudeng Mountain, they learned a new way of love: not relying on memory or guilt to maintain love, but becoming each other's eternal coordinates in their respective lives.
Intention: True love is to spend a lifetime actively choosing to stitch together the broken fates of each other repeatedly in the cracks of time until rebirth.
