The Twilight Between Us Netflix: Cast, Plot, Release Info

Gang Dong-won and Kim Go-eun will play heirs to two families locked in a century-long feud, married off by royal decree. Netflix announced the series, "The Twilight Between Us," on Thursday and said it has greenlit production on the romance-action period drama.

Kim Won-suk directs. Netflix lists his credits as "When Life Gives You Tangerines," "Misaeng: Incomplete Life," "Signal" and "My Mister." Park Ji-eun wrote the series, and Netflix lists her credits as "Queen of Tears," "Crash Landing on You" and "Legends of the Blue Sea." The announcement's own headline sells the project as coming from the makers of "When Life Gives You Tangerines" and "Queen of Tears."

Gang plays Mu-yeong, the illegitimate son of the House of Kang. He carries the title "Demon of the North" and lives in obscurity despite his martial skill and what Netflix calls a noble heart. Netflix says Gang's past roles span action, melodrama, thriller and fantasy, and that he brings both Mu-yeong's fighting ability and his emotional change to the part.

Kim plays Su-ryeon, the only daughter of the House of Han. After failing to become Crown Princess, she is bound by the royal marriage ban, and her union with Mu-yeong is an unforeseen twist. Netflix describes her as a woman who refuses to be subdued even after marrying into her family's sworn enemy. The king intends the match to end generations of conflict, Netflix says, but it soon spirals in directions nobody planned.

The title carries a second meaning. The Korean title's key word, hon, means marriage (gyeol-hon) but also the twilight hour just after sunset, when day and night blur together. Netflix says the story begins at the moment the two leads' fates become irrevocably intertwined.

The setup puts the two leads on opposite sides of an arranged marriage. Mu-yeong is a man of low standing with a fighter's reputation. Su-ryeon is a woman who lost her place in line for the crown and now answers to a royal order. Netflix gives the king a clear motive, ending generations of conflict between the families, and says the marriage soon goes in directions nobody planned. What the two do with a union neither chose is the premise the series is built on.

For viewers catching up on the leads before the series arrives, Soompi points to Gang in "The Plot" and Kim in "Yumi's Cells 3," both on Viki.

The announcement did not include a premiere date, an episode count, a supporting cast or a filming schedule. Netflix said only that the series is "coming soon."
