He stops her from eating the dumpling. He has never seen anyone who thinks this lewdly about food and a man. He grips her mind and commands her to close her eyes. "Noona, close your eyes. Think about your husband and how much you want to eat dumplings with him. Think about how much you want to...eat him. You can think lewdly without any limit. I will take you to the demon lord."
She starts screaming in her mind for her husband. His head hurts because of her.
[SUNG JUN, I AM STARVING FOR YOU.]
Choi Minho feels like crying. He has never met a person like her. Her husband's rival is food. He is wrong. He wouldn't want a woman like her. Ever. "Noona, how could a lustful woman like you cross lust easily? Why are you mixing food and your husband? I feel bad for him."
They manage to reach the demon lord. In the end, they get kicked out of Gluttony for offending the demon lord for disrespecting food.
