In a YouTube video from the channel 'Saego_F5-Duck Rice Bowl' operated by Changmin of TVXQ, the three artists Changmin (born 1988), Ryeowook of Super Junior (born 1987), and Kim Kyu-jong of SS501 (born 1987) reunited to share their golden era memories from the 2000s K-pop scene. The three agreed to be friends and created a warm atmosphere. They discussed the fan colors like Cassiopeia, ELF, and Triple S that symbolized each fandom, evoking nostalgia about Dream Concert's grandeur. They candidly discussed the rivalry between SM and DSP, and revealed the untold story that the dance team HG, who choreographed SS501's hit 'U R Man,' was originally TVXQ's dedicated team. They also shared their trainee struggles—Ryeowook confessed to losing 8-10kg in just two months after joining SM, eating only doenjang-jjigae. Regarding their peak achievements, TVXQ's personal fan cafes each had nearly 200,000 members while their official group fan cafe exceeded 800,000 members and was registered in the Guinness Book of World Records. Super Junior boasted their class by using private jets for overseas schedules. Kyu-jong mentioned SS501's achievement of performing at Tokyo Dome before their official Japanese activities and shared a bold anecdote about being blacklisted after urging fans during a live broadcast not to spend money on paid voting.
