The last time Lee Keum-seom saw her son, Ri Sang Chol, he was 4, as they fled the chaos of the end of the Korean War.
While Lee and her daughter made it into South Korea, Ri and his father were stuck in North Korea.
Lee and her son, now 92 and 71, were finally reunited Monday in North Korea, ending 68 years without seeing each other with a hug, and the knowledge that they had mere hours together to make up for a lifetime apart.
“How many children do you have? Do you have a son?” Lee asked her son, according to the Associated Press, while Ri handed his mother a photo of her late husband, saying, "Mother, this is how my father looked."
They were one of dozens of families seeing one another in person for the first time since fighting ended in the Korean War in 1953, and the peninsula was divided.
The fighting only stopped via an armistice, and a full peace treaty has never been signed, meaning the two countries technically remain at war.
Over the next few days, 89 South Koreans and 83 North Koreans are meeting at North Korea's Mount Kumgang resort, in supervised reunions that in total will amount to only several hours.
North and South Korea have held around 20 of these reunion meetings since 2000, but this is the first since 2015 — a result of the historic meeting between North Korean leader Kim Jong Un and South Korean President Moon Jae-in earlier this year.
Both countries had initially chosen 100 people each via lottery, out of many thousands who applied in South Korea, but some dropped out when they realized the family members they hoped to meet had already died, while others were too frail to make the trip north.
Writing on Twitter, President Moon said his administration would work harder to resolve the issue of separated families, including regular reunions.
The majority of those taking part in the reunions from the South Korean side are mostly in their seventies and eighties, with the oldest person involved a 101-year-old woman.
So for many, this marks the last time they will see their relatives again.
Speaking about her hopes for the trip before setting out, Lee, in a video released by South Korea's Blue House, said of her son, "He won't recognize me because he was only 4. We would only know each other by our names.
"When I meet him again I think I would like to ask, 'Where were you, how were you, who did you end up living with?'
"'You've done well growing up on your own — you must have missed your mom.'"
