In the midsummer of Qingying High School, Lin Xia and Lu Sichen started a two-way secret love under the cherry blossom tree. She hid 37 sketches of him secretly, and he quietly planned the trajectories of all "accidental encounters". Misunderstandings and secrets intertwined, and the unspoken confession at the graduation party was unexpectedly interrupted. The code of starry sky and cherry blossoms on the graffiti wall and the unsent letter in the drawer bury a promise that spans time. The sweetness and regret of youth precipitate in the process of growth. When the cherry blossoms bloom again, will those unfulfilled promises finally arrive? The open ending leaves endless imagination, and the most real throbbing and waiting of youth are hidden in the sweet pet.
Concept: The sweetness and regret of youth are nutrients for growth, and the unspoken love may continue in another way.
