SEOUL, South Korea -- On a Thursday afternoon in June 2020, two executives from the LG finance department arrived at the hilltop home of Kim Young-shik, the widow of the company's previous chair, for what was supposed to be a routine review of her family's finances. They sat at a long wooden table near the entryway, looking out at sweeping views of Seoul and a Japanese garden tended by the former chair, who had died two years earlier.
