KBS's new drama "Ohlala Couple" finally premiered on Monday.

The drama is about a couple whose souls become switched as soon as they sign the divorce papers and will deal with the realistic problems and stories of a couple that have been married for 12 years.

In the first episode, the two characters Na Yeo Ok (Kim Jung Eun) and Go Soo Nam (Shin Hyun Joon) were both seen in their past lives. In 1919, the two of them had fallen in love but was never able to consummate their love. Back in 2012, the two were now a married couple but they were constantly fighting. Na Yeo Ok was not being treated well by her in-laws and she said that she was going on strike, because she couldn't take it anymore. 

However, she was also seen taking on the role of a good friend when her friend Na Ae Sook (Ryu Si Hyun) came to her saying that her husband Lee Baek Ho (Choi Sung Guk) was also having an affair. At the same time, Go Soo Nam was a very famous and competent hotelier, attempting to appear as the doting husband but also having an affair with Victoria (Han Chae Ah). 

After deciding to live away from the family, she went apartment shopping and accidentally witnessed Go Soo Nam and Victoria. Shocked, she began having an asthma attack and decided to get a divorce. She ended up getting proof and they ended it. 

"Ohlala Couple" is a comedy that deals with a couple who experience soul switching. This is the first project for actor Bae Yong Joon's production company, 'Contents K.'

Shin Hyun Joon will show off his skills in comedy after many successful comedy movies and Kim Jung Eun will transform into a very outgoing and stubborn middle-aged woman. The drama, however, won't just focus on divorce but will emphasize the importance of family and the differences in the present and the past life.
