The late autumn wind blew the golden ginkgo leaves and fell on the window edge of the classroom on the third floor. Lin Zhixia sat by the window and watched Jiang Yubai, a young man always wrapped in a black hoodie, slowly walk from the last row to her seat - the fate of exchanging notes for tablemates began.
She is a Sagittarius girl who loves to smile and be cheerful on the outside, but is reserved when facing strangers. He is a nervous and dull boy who looks dark and distant, but hides a delicate and gentle heart. From when he stuffed the warm jujube water cup into her cold palm, to when she tugged on his sleeve and rode a pink electric car to take him to the station through the streets filled with ginkgo leaves; from when he used the "guessing the zodiac sign" game to trick her into thinking it was her birthday and urged her to solve math problems in a different way, to when he rummaged through the cabinets in his hometown and found a glass dip pen that had been treasured for many years, just to prepare a birthday surprise for her.
The care for each other when the road is blocked by heavy snow, the gentle reminders during class exercises, the chats on the way home from school... The tenderness hidden in the late autumn evening wind, the heartbeat falling on the ginkgo leaves, and the thoughts carried by the unsent glass pen, all gradually bring the distance between the two hearts closer. This is a story about youth, companionship and secret love. Like the warm tea that slowly heats up in winter, and like the brilliant bouquet of flowers that never fades by the window, it records the purest and most touching approach of two teenagers in their ignorant time.
