Moon River Season 1 Episode 4 Is Almost Here: Release Time and Where to Watch

The setup (and the big twist the show already dropped)

On paper, it’s a historical fantasy about a grieving crown prince chasing revenge after his wife’s death, until he meets a carefree merchant who looks exactly like his late princess. In practice, the show wastes no time pulling the rug: Episode 2 reveals Dal-I isn’t just a lookalike — she is the supposedly dead crown princess. She was ordered to take her own life, but her aunt Hong-nan saved her. To keep her safe, Elder Wolha — the mystical keeper of the red thread of fate — erased her memories. That’s not just spicy lore; it re-frames every stare-down and near-miss between Dal-I and Lee Kang.

Episode 2 capped things with a full-on rescue: Dal-I was wrongfully arrested and nearly punished, and Lee Kang stormed in with his men to pull her out. The chemistry is already sparking, and we’re barely out of the prologue.

What to expect from Episodes 3 and 4

"If episodes 1 and 2 explained the backstory of I-gang and Bak Dal-i, episodes 3 and 4 will develop the story in earnest and begin to weave the relationships among the characters more closely."

Translation: the table-setting is done. Now comes the messy part — secrets colliding, loyalties shifting, and that whole red-thread business getting tugged in ways no one can ignore. Good news if you’ve been craving momentum.

One more thing for streamers

If you’re watching online, new episodes typically land soon after the MBC broadcast. Subtitles on Viki can trail a bit, but they tend to be worth the wait.
