Multinational K-pop girl group Unis made a confident return with their new single "Curious," marking their first comeback since their debut on SBS' idol survival program "Universe Ticket" in March. At a press conference in Seoul, Yoona of Unis described the titular track as an energetic and dynamic song with an addictive melody, emphasizing its theme of breaking free from the old self to embrace a new persona. The group aimed to embody the characteristics of a Gen Z princess, showcasing a chic and confident image in their new album. In addition to the lead track "Curious," the single album features two side-B tracks, "Dating' Myself" and "Poppin'." According to Seowon, the youngest member of the group, "Poppin'" contrasts with the chic lead track, offering a bright and lively atmosphere with its bouncy guitar rhythm and groovy bass sound. Unis, which consists of members from Korea, Japan, and the Philippines, has garnered a strong international fanbase and recently named their fandom "Ever After," symbolizing their desire to create lasting memories with their fans through good music and shared experiences.
