Hidden in green hills east of South Korea's capital is the House of Sharing, a nursing home for elderly women.
It's a bright, spacious place. But its residents are survivors of a dark chapter of history.
"It was 1942 and I was only 15, running an errand for my parents [in our Korean hometown of Busan], when two Japanese men in uniform grabbed me by the arms and dragged me away," recalls Lee Ok-seon, now age 90. "That's how I became enslaved."
She was sent to work in a brothel in a Japanese-occupied area of northeast China.
