On May 10, 2017 (April 15, 2017 in the lunar calendar), Moon Jae-in was officially sworn in as the 19th President of South Korea. In the early morning of May 10, 2017, vote count data released by South Korea's Central Election Management Commission showed that the country's Common Democratic Party candidate Moon Jae-in won the 19th presidential election with a vote rate of 41.08% and was elected as the new president.

During the 2002 South Korean presidential election, Moon Jae-in served as chairman of the Busan Election Countermeasures Committee and made great contributions to Roh Moo-hyun's successful election. After Roh Moo-hyun entered the Blue House, Moon Jae-in was invited to serve as the chief civil affairs secretary of the Blue House, the chief secretary of civil society, and the chief of the secretarial office. In February 2008, after Roh Moo-hyun stepped down, Moon Jae-in returned to his hometown. On May 23, 2009, Roh Moo-hyun jumped off a cliff and committed suicide due to a bribery scandal involving his family. Moon Jae-in suppressed his grief and calmly announced the death of Roh Moo-hyun on live TV that day, leaving a deep impression on many South Koreans. Since then, he has been regarded as Roh Moo-hyun's political successor. In June 2012, Moon Jae-in quoted the old China saying,"Three years without singing, and one blockbuster will surprise you." He officially announced his participation in the presidential election that year. He attracted a large number of young voters with his affinity, but ultimately lost to his competitor "Ice Princess" Park Geun-hye by a slight disadvantage. In April 2016, Moon Jae-in made a comeback and led the Common Democratic Party to win 123 seats in the parliamentary election, becoming the largest party in the parliament. At the end of October 2016, the incident of "cronies interfering in politics" broke out, and the people had a strong desire for "regime change". Moon Jae-in leapt to the top of the list of potential presidential candidates in South Korea. On March 24, 2017, Moon Jae-in officially announced his participation in the presidential election, leading the way in the election and ultimately winning the election.
