Popular group INFINITE held a mini concert at Tokyo's Roppongi Hills as a special event for the fans who had purchased their new Japanese album. The boys kicked off the show with their debut track "BTD", followed by "Can U Smile", and "Be Mine". With fans screaming requests for encore performances, the members also performed their hit tracks "Paradise" and "Nothing's Over". Leader Sunggyu stated, "We're so happy to have debuted in Japan." The other members chimed in, "This is the best feeling. We're so thankful and happy." Member Dongwoo, who recently had his birthday, was surprised with a cake during the mini concert by the other members, and received a 'Happy Birthday' serenade from his fans. Prior to their official debut, INFINITE garnered strong interest in Japan, thanks to videos of their 'scorpion dance' from "BTD" gaining traction and their 'underdogs-to-success' story in Korea. They sold 70,000 pre-orders for their debut single, 'BTD', and then 15,281 copies upon official release. INFINITE ranked #2 on the daily Oricon chart, and #7 on the weekly chart with 26,333 copies sold. Source + Photo: Yonhap News via Naver
