With group artist 100% coming back soon, the leader Minwoo revealed a teaser image.

The first teaser image for "Want U Back' included Minwoo lying on a field of flowers with a half of his chest revealed, exuding a look of charisma and masculinity.

The manly, tough look on Minwoo is quite the opposite of his role in his recent showing on KBS TV series, 'Love and War.'

The management company announced, "We highlighted the rough and tough look in this teaser, trying to express the kind of sexiness that are not easy to capture for male artists."

100% will release their second teaser image on May 22 and make a comeback with their mini album and music video on May 23.
