Why did the once-celebrated fairy tale of true love across social classes in Korea turn into a five-year divorce battle? At the time, everyone doubted Lee Boo-jin’s choice. As the eldest daughter of Samsung Chairman Lee Kun-hee, worth billions, she insisted on marrying Yoo Jae-suk, a man from an ordinary background. Lee Kun-hee strongly opposed it, sitting alone in a hotel café all night. After marriage, the family tried to support Yoo by sending him to MIT to gain prestige. But he struggled to cope with the academic pressure overseas and was rumored to have attempted suicide twice by overdosing. Marital tensions gradually accumulated until the rift became irreparable. When the divorce proceedings began, Yoo Jae-suk demanded 1.2 trillion won (approximately 7 billion RMB) in asset division. This astronomical claim was ultimately rejected by the court. The legal battle dragged on for a full five years. In the final ruling, Lee Boo-jin paid 14.1 billion won (about 83 million RMB) to settle the divorce, with custody of their son awarded to her. What was once hailed as transcendent love turned out to be nothing but calculation—and now, the princess lives every day in regret.
