This drama follows the lives of two men and a woman through two eras: one during the 1930s Japanese occupation of Korea and the other in the 21st century. The three main characters are (1) Han Se Joo who was a writer in his past life and a bestselling author in the present. But Se Joo is depressed with writer’s block so he can’t write his next book. (2) Yu Jin Oh owned a bar in his previous life. In 2017 he is a talented ghostwriter who can bail Se Joo out of his predicament, but the mysterious man has a condition for his services. Se Joo may not be able to meet it. (3) Jeon Seol was a sniper. Now she has extremely varied expertises. She is a former Olympian hopeful, a veterinarian and a book lover who runs her own delivery service. She oscillates between extreme fandom and an anti-fandom of Se Joo. The intricately woven story of these three characters unfolds to reveal strange mirroring connections between the time periods as well as possibilities for past lives to be redeemed or improved in the modern world.
