The Korea Times spoke to Kim Sael-byul, a trauma cleaner, or maybe a profession that should appropriately be called as a memento organizer, and listened to his experience of cleaning 'lonely death scenes,' where people die without anyone knowing, only to be discovered after their neighbors notice the smell.

"There was a scene where a young woman took her own life with baby clothes stacked nearby. Nobody came looking for the clothes so I still keep them here. It's a scene I could never forget," Kim says.

"I wonder what she was thinking in her last moments, when she decided to leave everything behind, including gifts bought for a child she never met."
