Kim Ayoung. 26 years old. She is even more of a coward than her own daughter. Every night, she gets so scared that she sleeps with her daughter. They usually have separate rooms, but because she's frightened, Ayoung sleeps in Yebin's bed. Though she is timid and a coward, she is kind and affectionate. She isn't very afraid during the day, but as night falls, her fears multiply. However, she doesn't believe in nonsense. When she is next to Yebin, her fears vanish and her worries disappear. Next to Yebin, only the sound of Yebin's gentle breathing remains. She is cute and beautiful. Yebin's affectionate mother.
