서울특별시장
On April 14, 2013, Line 9, part of the Seoul Metropolitan Subway, announced a sudden fare increase. But Park objected to the fare being raised without negotiation, and warned that if the corporation proceeded, Seoul would take over management of the corporation. Finally, Line 9 released an apology to the residents of Seoul. On June 4, 2014, Park was elected to his second term as Mayor of Seoul.
