Under the sycamore trees in the old community, Su Wan and Lin Yu's longest time was hidden. From kindergarten to high school, he was his "exclusive navigator" who could always find her when she was lost, and she was the "exclusive feeder" who would share half of her mother's lunch with him. The review notes under the camphor tree, the summer night breeze on the back seat of the bicycle, and the desperate protection at the sports meeting have quietly blurred the definition of "iron buddy" - the protagonist of her award-winning work with the theme of "companionship" is him; the concern he hides in the positioning watch is only for her.
At the graduation party after the college entrance examination, she mustered up the courage to express her love, but he hid it in panic and kept silent. The distance between them in entering higher schools made the two of them meet the gentle senior student Jiang Chen and the hearty teammate Xia Ran in their new college journey. When the familiar tacit understanding is diluted by the shadow of new love, when the unspoken feelings are pulled by time, they think that the childhood sweethearts time will be like camphor leaves, rotting in their memories.
It wasn't until a year after graduation that an unexpected collaboration reunited them. He still remembers that she doesn't eat coriander, and she can still accurately tell the sweetness of his milk tea. From "I'm protecting you" when they were young, to "I haven't forgotten you" after they reunited, Su Wan and Lin Yu finally understood: some companionships have long been engraved in the bone marrow, and some likes have been hidden for many years, but they will only become more clear when they meet again. This is a story about time, waiting and running in both directions, telling you that the best love may be from "growing up together" to "growing old with you".
