This is a forbearing love hidden in time, focusing on the heart-pounding pull between Su Yuxing and Lu Chenyuan across the four seasons. The shackles of their teacher-student status and the concerns of worldly perspectives made the love between the two restrained from the moment they first met. They could only confide their concerns in secret corners, and tolerated and gave in within a short distance. The panic and retreat after getting close countless times, the long longing and concern in the late night, and the restrained and passionate embrace when alone, all hide the obsession that goes deep into each other's bones. From the cold winter to the end of summer, from hiding to the full light of the sky, they endured a long period of suffering and endured countless worries. Finally, when the shackles of identity disappeared, they took off all disguises and rushed to each other calmly, allowing the deep-buried love to bloom brightly, continuing to write the tender and long dependence of the years, and showing the perfection of the cautiousness and affectionate persistence in secret love.
