The teaser for FT Island vocalist, Lee Hongki's Japanese drama debut piece, 'Muscle Girl', has been released. Actress Ichikawa Yui, a familiar face in the Japanese drama scene, plays the manager of a weak women's pro wrestling organization. Lee Hongki plays her counterpart; this is Hongki's first appearance on Japanese drama. In the teaser, you can also check out FT Island's latest song and drama's main OST, 'Haruka.' 'Muscle Girl' is a youthful sports comedy about the world of women's pro-wrestling. A young female manager, along with a Korean super star that she met by weird fate and individualistic female wrestlers, takes on the challenge to transform a hopeless pro-wrestling group to compete against strong rival groups. Two women's pro-wrestling groups, Ice Ribbon and JWP, battle each other to add on a sense of reality. The drama will premier on April 19th on TBS and on April 23rd on MBS.
