Here Comes Mr. Oh

The drama juxtaposes two very different men who married two sisters. Oh Ja-ryong is a gregarious and good-natured fellow with a pure heart who is honestly devoted to his wife Gong-joo, while Jin Yong-seok married his wife Jin-joo because of her family's fortune and is now plotting to steal their estate. The jobless Ja-ryong stands up to his greedy and conniving brother-in-law Yong-seok, and saves his in-laws from ruin. [About] Here Comes Mr. Oh is a 2012 South Korean television series starring Lee Jang-woo, Oh Yeon-seo, Jin Tae-hyun, and Seo Hyun-jin.
