The tension between Yoon Yeo Jung and Kim Nam Joo finally leads to waterworks by both during a climactic scene.

In episode 42 of 'Unexpected You', which aired on July 15, Um Chung Ae (Yoon Yeo Jung) expresses her disappointment at her daughter-in-law Cha Yoon Hee (Kim Nam Joo). Chung Ae is upset that Yoon Hee did not say anything about her oldest daughter's divorce, even though Yoon Hee had known the entire time.

Chung Ae first becomes frustrated when Yoon Hee does not show up to cook at a family gathering. She demands that Yoon Hee immediately come over and start helping, while she allows her daughter Il Sook to rest. Yoon Hee is upset that she is treated differently from Chung Ae's daughter because she is her daughter-in-law.

Yoon Hee, who is already stressed due to her job, continues to ask Chung Ae if she has something to say to her. Yoon Hee tries to explain that it would be better to talk it out, but Chung Ae believes that Yoon Hee is disrespecting her.

Chung Ae finally asks about her daughter's divorce, "Why didn't you tell me if you knew?" She continues, "I know it's not your immediate family, but how could you just watch and do nothing?" To this Yoon Hee replies, "I am trying my best. I am trying to treat you as my family." This conversation then leads to tears.

At this moment, Bang Gwi Nam (Yoo Joon Sang) also gets made at his wife Yoon Hee and pulls her out of the house. However, later he explains to her that he had to get mad in order to "rescue her" from his mother. Through his caring words and actions, he continues to show that he is the "perfect husband".
