With Cho Sei Hyun as the photographer, the annual “Letters to Angels” campaign has revealed this year’s batch of photos featuring various K-pop stars. Every year for the past nine years, the campaign recruits several K-pop stars to pose with orphans, or “angels”, for an exhibit that promotes domestic adoption.

“The first angel is already nine years old,” Cho Sei Hyun said through his Twitter account. “This year, these days, a lot of stars and angels have played in front of my camera.”

The theme for this year’s campaign was “eyes,” and celebrities who participated included 2NE1, 2PM’s Nichkhun, BEAST’s Doojoon, Yoseob and Dongwoon, CN Blue, Choi Ji Woo, Park Shi Hoo, Kim Hye Soo, Lee Min Ho, Lee Seo Jin and SNSD’s Tiffany. The exhibit has not been opened, but behind-the-scenes photos have been revealed by Cho Sei Hyun through his Twitter.
