Oh Shin-hwan

Oh was re-elected in 2016, where his party faced a shock defeat. He was then appointed as the party's deputy parliamentary leader, but left the party after the political scandal in October. He then joined Bareun Party, the splinter group formed by Saenuri's dissidents. On 22 December 2017, he was elected as the party's parliamentary leader and held the position till the party was merged into Bareunmirae Party in 2018.

During the 2015 by-election, it was reported that Oh's master's degree from Korea University was revoked due to the thesis plagiarism, which he forgot to write the references. He mentioned that his degree was not revoked; he voluntarily returned it for parliamentary career.

The election of Lee Sang-kyu was annulled due to the UPP's ban in December 2014, which brought a by-election in 2015. Oh won the Saenuri preselection, defeating the former candidate Kim Cheol-soo. On 29 April, he gained 43.89% and defeated Chung Tae-ho (NPAD) and Chung Dong-young (Independent). The result became a sensation, as the constituency was known as liberal-leaning where conservatives did not win since the creation in 1988. Nevertheless, some analyses showed that he could lose if non-conservatives put a unity candidate.

Oh married to Yoo Jung-mi and has 2 sons — Oh Se-yoon and Oh Se-hyun. He is a Protestant.

Oh joined the Grand National Party (GNP; later Saenuri Party then Liberty Korea Party) in 2006, and ran as a Seoul Metropolitan Council member for Gwanak 1st constituency at the local elections. He received 43.75% and won, making him as the youngest person holds the position. In 2010, he was chosen as the GNP candidate for Mayor of Gwanak but lost to Yoo Jong-pil. In 2012, he was the Saenuri's MP candidate for Gwanak 2nd constituency but defeated by the opposition alliance (DUP-UPP) candidate Lee Sang-kyu. Following the defeat, he worked for Park Geun-hye, the Saenuri's presidential candidate who won in the same year, as well as the party's youth wing.

He attended to Danggok Primary School and Danggok Secondary School, then graduated from Danggok High School in 1989. Following the graduation, he studied civil engineering at Konkuk University but dropped out. He was then admitted to Korea National University of Arts (K-ARTS) and earned a bachelor's degree in theatre, as well as a master's degree in public policy from Korea University and a doctorate in urban sociology from University of Seoul. He graduated from K-ARTS in 1998 along with several notable actors, such as Jang Dong-gun and Lee Sun-kyun.

Oh had been acting in some university plays since 1989, while he was studying at Konkuk University. He joined Yeonwoo Stage in 1991, then subsequently appeared to Ride Together (동승), which was adapted from a drama of Ham Se-dŏk. After his admission to K-ARTS in 1994, he continued his acting in Marionette Show (꼭두각시 놀음), The Story of Park Ki-hong (박기홍 이야기), Mud (진흙) and so on. During this period, he worked with Song Kang-ho; a source reported that both used to share a house. Other than plays, Oh played supporting roles in independent films, including Yellow Flower (둘 하나 섹스) and A Woman Off Her Uniform (남산에 오르다).
