Answer Me, My Prince(2020)

Dapjangeul Juseyo, Wangja-nim

Cordelia Grey, an editor at a publishing company, is given a manuscript of the sequel to The Princess and the Knight along with a vintage chest. But when she wakes up the next morning, the manuscript she placed in the chest is gone -- a letter is in its place. It’s from none other than Prince Archie Albert, the handsome playboy and protagonist from the novel. What begins as curiosity morphs into a deep friendship, but can they stop themselves from developing feelings for one another, and will they ever get to meet in person?
