Kim Nam Joo of 'Unexpected You' was shocked after discovering the relationship between her younger brother Kang Min Hyuk and evil sister-in-law Oh Yeon Seo.
In the 42nd episode aired on the 15th, Cha Yoon Hee (Kim Nam Joo) witnessed the meeting between Cha Se Kwang (Kang Min Hyuk) and Bang Mal Sook (Oh Yeon Seo) while riding in the car on KB2 TV's weekend drama 'Unexpected You.'
On this day, Um Chung Ae (Yoon Yeo Jung) took out the wrath of her daughter Bang Il Sook (Yang Jung Ah)'s divorce on her daughter-in-law Cha Yoon Hee. Bang Gwi Nam (Yoo Jun Sang) could not bear to watch any longer as he brought Cha Yoon Hee out of the house to relax her.
As the two drove around late at night, Cha Yoon Hee observed Cha Se Kwang and Bang Mal Sook together and asked, "What are those two doing?" Bang Gwi Nam brushed it off, "They probably met coincidentally."
However, Cha Yoon Hee suddenly recalled the time she introduced the two, Bang Mal Sook unexpectedly becoming kind to her, Cha Se Kwang's words of breaking up with his girlfriend, and Bang Mal Sook's image while saying she hated herself the most.
Cha Yoon Hee felt her intuition and told her husband, "Honey, stop." The episode ended with Cha Yoon Hee finally figuring out the two's relationship and previewing her fury.
