Moon Jae-in is the only living former South Korean president who has not been arrested, but he is not without suspicion.

On the 26th of last month, South Korean President Yoon Seok-yeol was indicted by the prosecution on charges of masterminding a civil war. This is the first time that a sitting president has been arrested and indicted in South Korea, but it is the first time that a former president has been arrested and indicted in South Korea.
It is not uncommon for people to be arrested later, and of the three living former presidents, only Moon Jae-in has not been arrested. However, there are suspicions surrounding Moon, and in August last year
When the prosecution searched Moon's daughter's house, the search warrant specified Moon as a suspect in the bribery case. The South Korean president, who holds absolute power, is likely to be the target of criticism from opposition forces seeking a change of government.
In South Korea, whenever a new administration changes, the government intensifies its investigation into the corruption of the previous administration, a practice known as "political retaliation." For this reason, former President Lee Myung-bak was accused of bribery and his successor Park Geun-hye was arrested.
The former president, Park Geun-hye, was arrested for receiving bribes from a South Korean conglomerate. Meanwhile, Moon, who became president after Park, has not been arrested even after leaving office.
Before his retirement, Moon said about his life after retirement, "I will not get involved in politics and will live as an ordinary citizen. I will go to a nearby temple and hike in the Alps.
"I want to live my life climbing mountains, tending to my vegetable garden, and raising dogs, cats, and chickens," he said. "I want to be forgotten," he said, and live a life without the attention of the general public.
He hoped to live a peaceful life like other people. True to his words, Moon frequently posted pictures of himself working in the fields on social media. In 2023, he will be residing in Yamsan, Gyeongsangnam-do, a southeastern province.
He opened a bookstore that he produced himself near his private residence in Pyeongsan Village, Yangsan City. Recently, he has been frequently involved in political activities and statements.
When Lee Chun-sik, who won a lawsuit against Nippon Steel (formerly Nippon Steel & Sumitomo Metal) for damages, passed away at the age of 101, Moon released a comment on social media.
"Before celebrating his victory, Lee shed tears as he remembered his fallen comrades.
The memories of the incident are still fresh. The tears of sadness and joy were the tears of all of us," he said. "I remember how Lee Chun-sik's spirit of human dignity and indomitable will were so earnestly demonstrated as he testified about history.
I want to build a country that the next generation can inherit and be proud of." On the 30th of last month, Moon held a meeting with Lee Jae-myung of the main opposition Democratic Party at his private residence.
According to South Korean media, the two exchanged views for about 90 minutes on current political issues. This is the first time the two have met in person since September last year. Moon said, "We are in a state of extreme
"In this difficult political environment, integration and inclusion will be key to paving the way for the Democratic Party," he said.
In response, Lee said, "I empathize with that very much. I will do so." The Herald Business daily reported on Moon's advice to Lee, saying, "Recently,
"This appears to be based on concerns that conflict between the 'non-Lee Jae-myung faction' (who distance themselves from Lee) and the 'pro-Lee Jae-myung faction' (who are close to Lee) within the Democratic Party could intensify again."
When President Yoon was arrested last month, Moon mentioned this on social media, calling it a "victory achieved by the enormous solidarity of ordinary citizens," and in reference to Yoon's declaration of "emergency martial law" in December last year,
"It was very painful and embarrassing, but we have to use this as a new start," he said. Moon is the only one of South Korea's four presidents not to have been arrested.
However, Moon is also not without suspicion. In August last year, South Korean prosecutors indicted a former member of the Democratic Party of Korea National Assembly on charges of fraudulently hiring Moon's daughter's husband as an executive officer of an airline company he established in Thailand in 2018.
The daughter's home and other properties were searched. Moon is suspected of appointing a former member of parliament as chairman of a government-affiliated corporation in return for helping her family move to Thailand, including by hiring her former husband.
When his home was searched, the warrant listed Moon as a suspect in bribery. However, the investigation into Moon has been suspended. President Yoon, who declared "emergency martial law" in December, is currently undergoing impeachment trial.
The prosecution has been affected by the fact that he was indicted last month on suspicion of masterminding a rebellion. According to the South Korean newspaper JoongAng Ilbo, a source within the prosecution said, "In the aftermath of the impeachment of President Yoon, the investigation into former President Moon has been fully completed.
Before the Lunar New Year (29th of last month), Moon sent a New Year's greeting to the nation on social media. "The Lunar New Year will be greeted in a more difficult situation than ever before," he said.
"I hope this will be a year of fewer dividends and more smiles," he wrote. "We pray with one heart, as a nation, that the country will return to normal as soon as possible, and that our daily lives will return to normal."
"May the wounded and divided hearts of our people be comforted and healed, and our lives become more prosperous," he wrote. The post was prompted by President Yoon Seok-yeol's declaration of "emergency martial law."
This appears to have been done with the current political turmoil in mind.
