A delightful blend of romance, humor, and intrigue (as expected of many historical K-Dramas), this series takes us on a whimsical journey as Crown Prince Lee Yul, suffering from amnesia, is convinced to wed the headstrong Hong Sim due to his own decree. The drama plays into the comedic potential of his lost memory as he maintains his air of nobility—rendering him useless at daily chores and acts of labour to everyone’s dismay. As the effects of political secrets and conspiracies affect the poor of the kingdom, Yul begins to use his intelligence, martial arts skills, and literacy to help people learn and protect themselves. Doh Kyung-soo and Nam Ji-Hyun beautifully perform a fun enemies-to-lovers dynamic of a foolish prince and a justice-oriented woman. 100 Days My Prince delivers ornate kingdoms, cherry blossom-filled sets, and secret coups, all in a comfortable watch.
Lee Yool falls off a cliff and nearly dies in an attempted assassination. He loses his memory, and wanders for 100 days under a new name and personality. During this period, he meets Hong Sim, head of the first detective agency in Joseon.
