With just a week away until their 15th anniversary concert, Shinhwa showed that their passion and determination have not changed over the years through photos of them working hard in the practice room!

In addition to their more active choreography, fans can also see all six members sitting on chairs, possibly getting ready for their "Wild Eyes" performance or a touching ballad song that will bring fans to tears. Shinhwa previously sold out all 25,000 tickets to their concert within just five minutes, so there is no doubt that anticipation is running high for the event!

The concert entitled, '2013 Shinhwa 15th Anniversary Concert-The Legend Continues', will be held on March 16th and 17th at the Olympic Gymnastics Arena in Seoul!
