Kang Min Hyuk blames Kim Nam Joo for his break up with Oh Yeon Seo.

On July 14th's episode of 'Unexpected You', Se Kwang (Kang Min Hyuk) blames his older sister Yoon Hee (Kim Nam Joo) for his break up with girlfriend Mal Sook (Oh Yeon Seo).

As Yoon Hee and Gwi Nam (Yoo Joon Sang) return home and talk about Mal Sook, Se Kwang asks Yoon Hee carefully, "Your youngest sister-in-law's name is Mal Sook, right?"

He also asks, "What would you do if I dated a girl that you [Yoon Hee] really did not like?" She immediatly and curtly responds, "Of course I would not accept her".

He then blames her for his most recent break-up, as she replies, "You already broke up with your girlfriend?" and continues, "If you like her, you should just go ahead and date her."

He says that he broke up with his girlfriend because he knew his sister would not like her. At this she responds, "Of course I would not accept her if I didn't like her, but that doesn't mean you should break up with her."

The two continue to argue about this issue, when suddenly Gwi Nam interjects, "You two sound like a broken record." Yoon Hee then says to Se Kwang, "Don't I have the right to not accept her as your older sister?"

When Se Kwang asks if it is alright to continue his relationship even if she [Yoon Hee] does not like the girlfriend, Yoon Hee replies, "I have the right to not accept her as your girlfriend because I am your older sister. However, if you really like the girl, it would be stupid of you to let her go."

In the same episode, Mak Rye (Kang Boo Ja) becomes increasingly curious about Gwi Nam's torn baby picture, simultaneously developing viewers' curiousity on the subject.
