Zerobaseone, a popular K-pop boy group, is gearing up for the release of their fourth EP, titled "Cinema Paradise," next month. This comes just three months after the release of their third EP, "You Had Me at Hello." The group recently unveiled a teaser poster for the upcoming album on their X account and also shared a spoiler film on YouTube. The film features the nine-member group watching a movie in a theater, with a mysterious silhouette seen walking through a door. The subtitle "with special appearance" has sparked speculation about a potential collaboration with another artist. Having made history as the first K-pop group to achieve three consecutive million-selling albums on their release day, Zerobaseone is now preparing for their first world tour, titled "Timeless World." The tour will kick off with a three-day show in Seoul from September 20 to 22.
