Hwang Geum-byeol's mother. Mother of Geum-byeol and Min-su. A reckless fighter who uses her fists before words, and her feet before her fists! Her life was turned upside down in high school due to the misuse of her superhuman strength. She generally has many complaints and treats her husband like a servant while living a fun life, dressing up and enjoying herself. She is flashy, beautiful, and immature. Strong on the outside, strong on the inside. An invincible 'tough sister' whom no one can touch! The person who passed the superhuman strength down to Hwang Geum-byeol. She herself was famous as a weightlifter in her youth, contributing to national prestige with her strength. However, she dismissed the family tradition—that one loses their strength if it is used for selfish greed—as mere superstition. She extorted fellow students and exchanged the gold medals she won at competitions for cash at jewelry stores to enjoy luxury shopping, only to lose her strength overnight. However, the strength seems to be hereditary as she passed it on to Hwang Geum-byeol. She regretted it quite a bit after losing her strength and mentioned that she rebuilt her power by starting again from light weights. Seeing as she threatened to kill a gangster who punched her in the stomach, it seems she still has some degree of strength left, though not as much as before.
