A black umbrella in a heavy rain caused the life trajectories of designer Su Wan and lawyer Lu Xingchen to quietly intersect. From the meeting downstairs in the office building to the time spent together under the wisteria trellis, they spent a lifetime turning the "late starlight" into a long-lasting warmth. This love hidden in the design drawings and files spans four generations. Witnessed by the star trails and wisteria flowers, it has become an eternal light of life.
