Five-member group AND2BLE (Hao, Seung-eon, Ricky, Gyubin, Yujin) released a special video for 'Happy &' from their debut mini album 'Sequence 01: Curiosity' on their official YouTube channel on the 11th. The video captures footage from their showcase concert '2026 AND2BLE SHOW CONCERT: Welcome to Qurious,' which successfully concluded in four Asian cities (Seoul, Yokohama, Kobe, and Macau). The video features members moving through the audience, making eye contact and singing together with fans, creating an intimate concert experience. 'Happy &' is an alternative pop singalong fan song that evokes warmth of spring and sensitively portrays the excitement of a miraculous encounter. Both Macau concert dates sold out completely, demonstrating AND2BLE's growing global popularity. The group continues to engage with fans by releasing their own content series 'D2BLE CLICK' every Wednesday at 9 PM on YouTube.
