"We gathered once every three months. When we met last time in March, somebody suggested a trip to celebrate our 60th birthdays to Jeju," Kim said from a hospital in Mokpo, where he was being treated for a fracture in a rib bone.
In South Korea, as in many other countries, 60th birthdays are often celebrated as a milestone in one's lifetime.
"We wanted to make some memories with old friends," he said, recalling the lipstick prank and the funny characters his buddies drew on his arms while he was sleeping. One of his friends took a picture of him and sent it to him on a mobile phone, but it too was lost as the ferry flipped on one side and sank in cold waters.
Nine people, including five students and two teachers, have been confirmed dead, 287 are still missing and 179 have been rescued. There were 475 people aboard, including 325 students on an overnight school trip to Jeju, a tourist island. They were from Danwon High School in Ansan, which is near Seoul. Kim's group came from Incheon Yongyu Elementary School.
For Kim, who works in the food business, it was his first sea journey, and his first big trip since he traveled to China on a plane a decade ago.
He said that his 12 missing buddies were like brothers and sisters to him — they've remained close for about 50 years, meeting regularly, making plans together and carrying their childhood friendship into old age. They had been planning a much bigger overseas trip in the fall, this time with their spouses.
Among his friends, Kim said he missed Baek Pyung-kwon most.
"He didn't even drink and he helped other people in difficulties a lot," Kim said. "He was not even rich but he made a lot of donations when he watched stories of people in difficulties on TV. He did a lot of volunteer work."
Another of Kim's missing friends was an elder at a church, a devout Christian who also spent his time volunteering.
