On this day, Oh Chang Min took hurt Oh Jin Hee home. Oh Jin Hee's sibling Oh Jin Ae (played by Jun Soo Jin) and her spouse who saw this called for his brother-in-law and invited him to the house.
At this, Oh Jin Hee said, "What do you mean, "brother-in-law". Just call me brother" and corrected how to call him. However, Oh Chang Min didn't particularly dislike the "brother-in-law" phrase and said, "Call me as you wish."
