Chen Yuxuan is the eldest son of the Chen family. He is two years older than Chen Lan and always looks mature.
Chen Lan was afraid of him because he rarely smiled. Even when he got a perfect score, he just said "don't be proud". Until he accidentally opened Chen Yuxuan's sketchbook hidden in the drawer, and every page was of him: him running in the playground wearing a straw hat, squatting by the flower bed to feed the cat, and even the little hat made of straw stalks that he secretly placed on Chen Yuxuan's desk on his birthday.
The last page depicts a campus in late autumn. Chen Lan is standing under the ginkgo tree wearing a straw hat, while Chen Yuxuan is standing behind him, with her fingertips almost touching the ends of his hair. There is a line of small words written on the corner of the drawing paper: "If you want to take it off, hide it in your pocket."
After school that day, Chen Lan deliberately left her straw hat in the classroom. When Chen Yuxuan chased him out, he was standing on Wutong Road waiting for him, and the ginkgo leaves on the brim of his hat rustled down. "Brother," Chen Lan raised her face, her voice as soft as the wind, "Would you like to help me take off this hat?"
Concept: The straw hat is a relic of Chen Yuxuan's sealed past, and it is also a container for him to hide his feelings for Chen Lan. From the forbearance of secretly photographing their backs to the declaration after the secret of their identity is revealed, the two break the prejudices of blood and secularity and redefine "family" and "love" - the real bond is the courage to get close to each other in loneliness, and the warmth retained for each other in the withering autumn scenery.
