Accidentally, he learned of his wife's dark past through his sister-in-law's diary, and this leads to a reversal of the relationship with her sister-in-law. Min-sang began to demand excessive demands from his sister-in-law, and Yu-mi began to accept them. Where will the end of the relationship between Min-sang, Yu-ra, and Yu-mi lead?
