Scarlet Heart: Ryeo (Season 1)

Scarlet Heart: Ryeo (2016) is a Korean historical fantasy drama you can watch online on iFILM, directed by Kim Kyu-tae. During a solar eclipse, 25-year-old Go Ha-jin is pulled back in time and wakes up inside the body of a noblewoman named Hae Soo — stranded in the royal court of the Goryeo Dynasty, roughly a thousand years before her own era.

Hae Soo, played by IU, finds herself surrounded by princes fighting for the throne of King Taejo's court. The scarred and feared Wang So (Lee Joon-gi) draws her in despite — or because of — his ruthless reputation. Kang Ha-neul brings warmth to the rival prince Wang Wook, making the love triangle feel genuinely painful rather than decorative. Political survival and the pull of a doomed romance drive every episode forward.

The show's tagline — "I'll be waiting for you, even if it's for a thousand years" — sets the tone precisely. South Korean broadcaster MBC aired 20 episodes in 2016. Stream Scarlet Heart: Ryeo online on iFILM.
