The Moon Sets (달이 지다, Dari Jida) is chapter 44 of the Twelve Nights webtoon.
The villagers are troubled by the rising of a red moon, but they later somehow treat it as an auspicious sign after thinking of it as Crown Prince Jin Yeon's arrival. However, Hwi is greatly distressed for the rebel army, since their headquarters is set on fire. There, the rebel army seek refuge from a nearby mountain but are also thwarted by the Bi Yeong Pal Mu headed by Heuk Rang.
Meanwhile in Yu Hyang Ru, the rest of the Bi Yeong Pal Mu led by Baek Ah surround the gisaeng house, either capturing everyone or killing those who resist. Seol Hwa, who resists to be captured, is rescued by Wol Young Hwa after the latter stabs a royal guard. However, Seol Hwa is hit by an arrow; as Young Hwa calls for help, the guard earlier stabs her with his sword. Hwi arrives and kills the guard, escorting Seol Hwa and Young Hwa out of the place. Because of her wound, Young Hwa chooses to leave herself behind to have Hwi leave quickly with Seol Hwa. As she closes Yu Hyang Ru, Bi Yeong Pal Mu archers fire on her.
Rok Ha and Gyeom watch from a distance, as Rok Ha announces that their deal is over as of that day. Baek Ho meets Hwi on the mountains, but the latter returns to Yu Hyang Ru as he promised to Young Hwa. He notices his foster mother dead and grieves for her. In the end, the rebel army suffered complete defeat three days prior to their planned revolt.
