A gaze that started in a cafe allowed her to follow his poetry through the streets, bookstores and dusk. A heartbeat that started with a tacit understanding allowed him to understand her deep feelings hidden in waiting. Letters are sent to the south of the Yangtze River, and thoughts fall on the pages. All the thoughts hidden in the singing of Kunqu opera, ink marks, and fallen leaves finally blossom and bear fruit in the wind of the beginning of spring. This is a regret about waiting.
Concept: The ultimate beauty in the world has a shelf life, and regret itself is also a part of romance.
