K-pop group Red Velvet achieved a complete sell-out for their fan concert 'A Day in Red & Velvet' through pre-sales alone, demonstrating their strong popularity. The concert will be held on August 1st at 6 PM and August 2nd at 4 PM at Korea University's Hwajung Gymnasium. Ticket reservations through Melon Tickets sold out rapidly, including obstructed view seats, based solely on domestic fanclub pre-sales on the 18th and global pre-sales on the 22nd for both performances. This exemplifies Red Velvet's solid fanbase and ticket-selling power. Notably, this fan concert marks their first complete lineup performance in approximately 2 years and will be a meaningful occasion to celebrate their debut anniversary (August 1st) with fans. Additionally, Red Velvet is reportedly preparing for a new album release in August.
