Signs of the times**: Faye Wong's "The Book of Laughter and Forgetting" is floating in the underground karaoke hall of the millennium, the corner milk tea shop uses non-dairy cream to prepare the taste of first love, and faded sheets are dried on the rooftops of old-style residential buildings. These symbols of the times will bear witness to love that spans ages.
- **Character Arc**: When Lin Jianyang, a young architecture student, was drawing the city skyline, he met Su Qinghe, who was dancing alone in the folds of time. The tear stain at the end of her eyes hides her unfinished dance dream, and the sketches in his sketchbook record the trajectory of her heartbeat.
- **Emotional growth rings**: From holding oil-paper umbrellas in autumn rain to sharing roasted sweet potatoes on winter nights, from flying paper kites by the river in early spring to counting shooting stars in midsummer. When the train for the graduation season was about to pull into the station, the sister who always said "it's too late" let go of her hand when the parasol trees were flying.
- **Intertwined images**: wrinkled movie ticket stubs, yellowed piano scores, faded dance shoes and architectural models sleep together in old cardboard boxes. The sweetness of non-dairy milk tea and the saltiness of tears turned into the amber of youth in the neon of the underground singing hall.
Intention: Lament for fate but not destiny
