You Who Illuminate My Darkness.
“Cheong-Jo, how could you leave me here all alone? Where on earth are you right now?”
Amid consecutive years of famine, when even a single meal a day is hard to come by, a mysterious middle-aged man approaches Cheong-Jo and offers her the position of a concubine. Determined to pay for her mother’s medicine and support her younger siblings, Cheong-Jo follows the stranger deep into the mountains. There, she meets the man who will be her husband, but... Do-Un, a man shrouded in secrets who wears a black mask, despises and humiliates Cheong-Jo.(Source: Naver Series, translated)
