In the elevator of the inpatient department of the city hospital, Chen Mo, who was suffering from viral myocarditis, accidentally met Lin Nian, a girl wearing a beige knitted hat and waiting for her hair to grow out, because of a missing blue piece of the "Sunrise by the Sea" puzzle. During the brief exchange, Lin Nian took the initiative to invite Chen Mo to ward 307 to "exchange stories and listen". Chen Mo not only completed the puzzle with the pieces, but also put it into his notebook to treasure this warm first encounter in spring.
Concept: With the hospital as the background, through the exchange of puzzle pieces and stories, it shows the healing power of strangers comforting each other and illuminating each other in troubled times.
