Jiang Ning, a children's picture book editor who works late at night, discovers a strange man downstairs in her apartment. The young doctor who always wore a white coat would stuff envelopes into the abandoned mailbox at five o'clock every morning and take them away on time at seven o'clock. Until one day during the rainy season, the mailbox deformed due to moisture and got stuck in his brown paper bag.
On a night of heavy rain, Lu Chenzhou knocked on the door of Jiang Ning's house, soaked to the skin with water droplets on his eyelashes: "Can I borrow a hair dryer? These letters... Must not get damp." Amid the roar of the dryer, Jiang Ning caught a glimpse of the tender handwriting on the yellowed envelope: "The 88th letter to Sister Moon."
It turns out that this cardiac surgeon, who is as cold as a scalpel, has been sending undeliverable thoughts to the children in the orphanage for ten years. And what he said about "helping easily" hides the secret of his childhood watching people coming and going through the glass window.
When the starry sky mailbox designed by Jiang Ning was completed in the welfare home, Lu Chenzhou showed a melting smile for the first time: "Now it's the moon's turn to reply." He opened his palms, and 365 hand-folded stars flashed under the street lights. Each one opened with the same line of words——
"I also want to meet Jiang Ning today."
