Moon Lovers: Scarlet Heart Ep. 18 (Patreon)

Wang So considers proposing to Hae Soo, but she stops him, knowing that she can't be an empress with a scar, and she won't ask him to give up the throne. Meanwhile, Yeonhwa continues her manipulations behind the scenes, pushing closer to marrying So and securing her power.

Things take a devastating turn when Soo’s maid, Chae Ryeong, is exposed as a longtime spy. So orders her brutal execution, and Soo walks in on the aftermath — completely shattered. The betrayal and violence become too much, and though So still loves her, Soo starts emotionally detaching. The gap between them deepens as she sends word to Jeong.
