Han Seungyeon became a rocker.

On MBC "Music Core," KARA's Han Seungyeon performed her solo song, "Guilty."

KARA recently released a special album, KARA Solo Collection, with each of the members' solo songs. Han Seungyeon said, "In the song 'Guilty', I contained my desires to have a strong heart, not shaking easily."

She threw away her soft and cute image that she had until now and transformed into a strong woman rocker.
