The Royal Fortune-Teller, Open in Seoul for 600 Years

Three months before her contract runs out, webtoon producer Yoon Da-on storms into a fortune-telling shop at the end of an alley. The coldly handsome owner predicts what will happen three days later from her birth date alone, because he once read fortunes for the royal court of King Sejong. People say it's his punishment for revealing heaven's secrets, and he says the same. But what has he really seen in 600 years, and what was he trying to do when time stopped for him? With every client's fortune he reads, another piece of his secret comes to light.
