Hyun-min's grandmother and the main character of a strange life. She lost her husband to an illness, and she struggled for the rest of her life, raising her son alone. When she lost her son and her daughter-in-law in a fire, she wanted to die, but the reason she didn't die was because of her miraculously surviving young grandson, Hyun-min. The thought of raising her son and her daughter-in-law, who left early, made her even more pampered. Hyun-min grew up steadily, but Ok-soon grew old faster than that.
However, she starts to say strange things about Ok-soon from time to time. It was her villagers who killed her own son and daughter-in-law. Her people pretended not to hear it, saying that it was only because of her dementia, but her hatred towards her villagers and her boundaries are growing.
