A broken stringed harp in the museum reveals a time-defying obsession that spans thousands of years. Modern history writer Shen Buyan, in order to clear up the historical fog of Lu Yuan, the "demon queen" of Nansheng Kingdom, was accidentally involved in the vortex of time and space by the Pisces Ring, but encountered the cruelest paradox of time and space - he came back in time, and every time he met, he met her younger; she grew up with the years, and every time they met again, she forgot his love a little more.
From the dying queen of Jiangdu, to the ignorant girl with haircuts in her boudoir, he was full of heartache and obsession, wanting to change her fate of death, but every intervention became a push to push her into the abyss. The undercurrent of palace intrigue, the pressure of the family's rise and fall, and the regret of time and space finally reduced him to a passing guest in her life.
In the last peach blossom shower, at the age of eighteen, she stepped into the palace wall wearing a gorgeous dress and carrying a brand new harp, and was completely unfamiliar with him. The sound of a string breaking is a farewell from thousands of years ago and a sigh that spans time. The Pisces ring has lost its luster, and the broken string of the harp has been lying dormant for thousands of years. He spent his whole life compiling history books just to restore her truth, and that period of lovesickness against time has finally become the unfinished perfection in the sound of the piano.
