Celebrating the 15th anniversary of SHINee’s debut, unveiling the deepest heart-to-heart story of 'SHINee' and 'Us'. Formed by SM Entertainment, SHINee is a boy band that debuted in 2008 with "Replay". The Korean idol group has made a recent comeback with its eighth album "HARD", which has made headlines by topping the iTunes Top Album Charts in 43 countries. "My SHINee World" will include behind-the-scenes footage from the concert preparation to the on-stage performances of the group’s recent concert, "SHINee WORLD VI [PERFECT ILLUMINATION]" held at the KSPO Dome. In addition, there is a variety of unreleased content as well as heart-to-heart interviews to watch SHINee's 15 years of history at a glance. As the production crew placed the most importance on storytelling that fans can relate to, the movie follows SHINee's history in the eyes of "the fans" and gives them a chance to reflect on "My 15 Years" as well as "SHINee's 15 Years".
