Jasmine and Wutong have been together for twelve years, witnessing the profound love between Xie Linyuan and Shen Shuyi. When ten-year-old Shen Shuyi met 22-year-old Xie Linyuan, he became the only salvation in her pale life, the lingering moonlight in the dark night. From then on, they began a long and entangled life. When she confessed her love to him while wearing the star and moon pendant he gave her, he pushed her away because of the "age gap" and "secular ethics." However, he hid another thorn and jasmine pendant deep in his heart, locked his love into the identity of "brother", and used deliberate alienation to cover up his turbulent heartbeat. When he finally dared to put aside all worries and restraints, he lost forever the girl he loved his whole life.
When the jasmine is gone and the sycamore trees are covered with frost and snow, the star and moon pendant is not yet complete. Their love was ultimately trapped in the shackles of the world and became a lifelong regret of "too early to meet and too late to confess".
They were not together in the end, but they never left each other's lives: in her later happiness, there was the light he gave her back then; in his protection, there was his lifelong regret. This love was inevitable and unsolvable from the beginning - it must be because their bond has been engraved in the bone marrow, and unsolvable because the shackles of ethics will always lie in the middle.
But this "no solution" is precisely the best redemption: he spends his life practicing "guarding", and she spends her life proving "light". In the end, they live the most gentle and regrettable fate in each other's lives.
The phoenix trees in the courtyard turned yellow year after year, but they always protected his little Jasmine. Their bond will always remain in the fate of "light and shadow", gentle and long.
