During KARA's concert on the 18th and 19th at the Seoul Olympic Stadium.

During the opening concert, Han Seung Yeon revealed something that hasn't been seen in a while. It was Han Seung Yeon's tight abs. On stage, she was wearing yellow pants with one side rolled up to the knee matched with an unbuttoned red and white checkered top with a white tank top underneath.

Netizens who saw the photos of her abs responded with comments like, "Wow! Words can't express..", "I can't believe she's been hiding those abs all this time!" and etc.

Members of KARA began their very first exclusive concert as well as their first exclusive Asia Tour. For KARASIA, KARA members will travel to China, Hong Kong, Taiwan, Thailand, Japan and more. KARA will perform in five different cities in Japan starting in April.
