A century ago, fate was a bear trap and love was a spear.
1907, Joseon Korea: Lady Yeong-sil, the cherished daughter of a powerful official, falls recklessly in love with Yi Haneul, a poor, soulful musician whose melodies are her only comfort. Their forbidden love ends in a desperate, fatal flight to the sea, where Haneul is brutally murdered by a spear-thrower hidden in the night, and Yeong-sil drowns herself in grief. Their tragic end leaves one agonizing question unanswered: Who was the killer?
2025, Seoul: Haneul and Yeong-sil are reborn, living separate, modern lives, haunted by no memory of the past except for an intense, inexplicable loathing that flares the moment they meet. But the vicious, unseen force that tore them apart a century ago has also returned.
As the echoes of their past life pull them toward an irreversible confrontation, they must uncover the truth about 1907 before the killer reincarnated and hiding in plain sight can finish the bitter melody they started long ago.
