SBS drama 'Ghost' introduced a new couple also known as the 'mijjo couple.'
The name was derived from combining the Kwak Do Won (played by Kwon Hyuk Joo)'s nickname of 'michin soh (mad cow)' and Choi Seung Yeon (played by Song Ha Yoon)'s nickname of 'jjorin gamja (cooked potato).'
Kwon Hyuk Joo got the nickname 'michin so' from actively pursuing investigations for reported incidents like a mad cow who's after one goal. On the other hand, Choi Seung Yeon's nickname of 'jjorin gamja' was derived from captain Kwon's tendency to call reporter Choi that alias when both demanded to know the progress of the investigation.
It seems that as captain Kwon and reporter Choi work alongside in investigating the case of Shin Hyo Jung, the two will eventually draw closer together.
Audience of 'Ghost' mentioned, "This drama draws anxiety because of its unpredictability, but the casting of Kwon and Choi brighten the mood and makes it more fun to watch." Another noted "I want to see more of Kwon Hyuk Joo and Choi Seung Yun's unfolding love relationship."
At first, there was a concern to whether the two individuals will be fitting in a romantic relationship but with Kwak Do Won's playful acting, it wasn't an issue anymore. Song Ha Yoon thanked Kwak Do Won for making her feel comfortable in filming for the movie.
