In a world where memory shapes destinies, two individuals stand at opposite ends of remembrance. Jeong Hoon, played by Kim Dong Wook, the handsome news anchor with hyperthymesia, remembers every detail of his life and is haunted by the disappearance of his beloved Seo Yeon eight years ago. Meanwhile, Ha Jin, portrayed by Moon Ka Young, a rising star in the public eye, grapples with a fading memory that challenges her daily existence. Despite her struggle, she lives her life with confidence. As their paths converge, these individuals confront a journey of comprehension, acceptance, and the possibility of unexpected bonds, where memory becomes both a bridge and a barrier to their destinies.
