When he was six years old, Lin Muzhou wrote in his composition: "My wish is to grow up and marry Shen Niannian." The teacher thought it was homework, but only he knew that it was true.
Shen Niannian and Lin Muzhou have known each other since they were wearing diapers. The two families live across from each other, and their parents are best friends. They planted the sweet-scented osmanthus tree together and grew up together. She thought he was just a tough-talking, soft-hearted brother next door, but she didn't know that he had saved an encrypted photo album since the first year of high school, and it was all about her; he gave up a better university for her, and shouldered all the rumors by himself, but he didn't even dare to say "I like you."
It wasn't until she gave up on A that he finally spoke: "It's not like it, it's love. It started a long time ago."
But love is never a matter of two people. A jealous school beauty, an unwilling old friend, a well-designed trap... When the conspiracies in the dark strike again and again, can they keep this twenty-year agreement?
From wearing diapers to wearing wedding dresses, from childhood sweethearts to the love of life. This is a story about waiting, guarding and running in both directions. When it's sweet, it's like sweet-scented osmanthus candy, and when you cry, it's like a rainy night, but in the end you will find that the sweetest candy is the one who grows up with you and grows old with you.
