The 29-year-old Bae Zhili is the only son of the Bae family. On the surface, he is a ruthless business machine. He hates sunny days, but hidden deep in the safe is a yellowed children's picture album. When he was kidnapped at the age of 12, the girl next door handed him graffiti through the ventilation duct. The title page reads "For the children on cloudy days." The burn scar on the ring finger of his left hand was the mark left when he tried to burn the album.
The 24-year-old illustrator Jiang Linxi, whose online ID is "Sunny Doll", uses his paintbrush to heal others, but is afraid of the black umbrella due to the deafness in his right ear and the kidnapping shadow. Hidden in the corners of all her works is the same date, the day of the kidnapping. She didn't know that the sun drawn on a paper towel with half a blue crayon had become the only light in Pei Zhili's darkness.
Fate brings them back together. He acquires a weather company just to predict sunny days (she needs sunshine for sketching), and she publishes "It will be sunny tomorrow" illustrations every rainy day in his city. When the media exposed the truth about the kidnapping case, the confrontation on the rooftop in the heavy rain ripped away the pretense.
Pei Zhili's mother created the lie that "the hostage was dead" to protect her son, and the last page of the torn-out picture album was the agreement they made when Pei Zhili was 12 years old: "Let's watch the sunny days together when we grow up."
Concept: The deepest scars hide the gentlest redemption - when two broken souls recognize each other in the haze, even the scars become the starlight that illuminates each other.
