Girls' Generation's Seohyun made a surprise appearance during the North Korean Art Troupe concert.

On February 10, the North Korean Art Troupe held their last concert in Seoul at the National Theater of Korea. The audience was clearly enjoying the show but was further shocked and impressed when a member of one of K-pop's greatest groups ever, Seohyun, stepped onto the stage to perform with the North Korean team to signify unity.
