On March 27th, it was revealed that singer Chae Yeon made a surprise visit to the set of KBS's "Qualification of Men" to cheer on their ramyun contest - gathering much interest from the public. The contest was set up like a tournament with eight contestants in a 'final four' like format. Chae Yeon arrived during Lee Kyung Gyu and Seung Hae's battle, and as it so happened, she was a neighborhood unnie (older sister) of contestant Park Seung Hae, who was close to her. Chae Yeon waited for five hours to cheer on her dongsaeng (younger sibling) - sending her a loving message. Chae Yeon stated, "It would be good if you beet Lee Kyung Gyu and went all the way. That way, I can cheer you on till the end." After, she decided to stay on set to directly cheer her dongsaeng on - displaying an even greater nervousness than the contestants. Source: Osen
