The summer days in Wutong Lane are wrapped in the fragrance of locust flowers and the chirping of cicadas. The sweating figure of the boy on the basketball court and the concentration of the girl writing in the studio, under the shade of the old locust tree, weave a two-way journey that spans youth and years. Lin Weiran, a gentle girl with a dream of painting, uses the paintbrush as a medium to freeze the high-spirited basketball boy Jiang Yi in the light and shadow of midsummer; Jiang Yi, a passionate and sincere basketball player, always regards protecting Lin Weiran's dream as the most important agreement in his heart on the court and on the track of life.
From the youthful excitement on the high school campus, to the longing for a foreign country across the sea; from the perseverance of starting a business side by side in Wutong Lane, to the tenderness of the sophora fragrant flowing through the red carpet at the wedding; from the daily fireworks of a pair of children around the knees, to the romance of a family of four running to Iceland to chase the aurora, and then turning love and passion into charity fire, illuminating the dream pursuit of children in mountainous areas - their stories contain the purest throbbing of youth and are filled with the longest perseverance over time.
The scent of paint in Huaixu's studio, the cheers of the basketball training camp, and the years spent under the old locust tree have witnessed the growth and inheritance of two generations. From a young boy to an old man in his 60s, from two people staying together to four generations living together, they have spent decades proving that the best love is when each other becomes a better version of themselves; the most beautiful life is when love is blended into fireworks and the original intention illuminates the way home. Stars fall into the summer, cicadas chirp, and time settles the fragrance of locust flowers. This is a narrative about youth, dreams, love, and inheritance. In the smoke and smoke of Wutong Lane, it tells the warmth of the flowing water and the tenderness that never ends.
