K-pop boy group TVXQ held its special live tour "T1STORY" at Seoul Olympic Gymnasium in Seoul Sunday.
The boy group's Seoul concert was held in celebration of its 10-year career.
At the concert, the group performed its hit songs, such as "Keep Your Head Down" and "Catch Me." The group members also sang all the tracks from its seventh album "TENSE," which was released in January.
All the tickets were sold out instantly after the ticket sales started on Oct. 28, due to TVXQ's incredible popularity.
Prior to the concert, TVXQ member Changmin hinted in a news conference that he prepared a surprise performance.
"I will expose my upper body onstage," the Korean heartthrob said, wowing the crowd. "I hope you like it."
The singer added that he has been refraining from drinking for the past two months in order to stay fit for the concert.
"My personal trainer forced me to avoid (salty food, such as) soup, stew and even Kimchi," he said.
TVXQ is slated to hold the next concert in Taipei, Taiwan, on Dec. 13.
