Actor Koo Sung-hwan reunited with his high school girlfriend after 30 years, as a long-forgotten promise to marry each other was revealed.
On the Nov. 13 episode of MBC's variety show "I Live Alone," Koo attended a high school reunion, where he met his first love, identified as Cho-hee.
Before she arrived, his friends teased him, saying, "You two are the only ones who aren't married yet," and "Didn't you two date?" Koo appeared flustered and asked them not to bring up the subject when she arrived.
His friends also recalled how Koo once gave her a ring and carried her on his back for about 5 kilometers to take her home.

In an interview with the show's production team, Koo said they had dated for 50 days in high school.
"I liked Cho-hee so much. I confessed to her in front of a playground, saying, 'I think I like you,'" he recalled. "It was a very innocent romance. Even after we broke up, I still had feelings for her for a year, but she didn't accept me."
When Cho-hee arrived at the reunion, however, she said Koo had been the one to end the relationship. She also revealed that they had repeatedly made a marriage pact.
"In our 20s, he would call me all the time and say that if we weren't married by 30, we should marry each other," she said. "But when we reached our 30s, he changed it to 40."
Webtoon artist Kian84 said, "That's what people who really have feelings for someone tend to do."
Host Jun Hyun-moo then asked Koo whether he would consider marrying Cho-hee if neither of them had married by the age of 50. Koo could only smile shyly.
Explaining why he had ended the relationship, Koo said he had seen friends break up and never see each other again.
"I was afraid the same thing would happen to us," he said.
