They first became known as idol singers, but once they broadened their activities, they became multi-players.

Group B1A4's Baro first tried his hand at acting last year. He starred in the drama "Respond 1994" as a medical student from Chungcheongdo. Despite being from Jeollado himself, Baro spoke with a Chungcheongdo accent for his role. Baro was recognized for his way of speech and facial expressions in dealing with internal conflicts in the drama.

After the drama was concluded, Baro returned to his group as a B1A4 member and released their 2nd full length album. They took home the number 1 trophy with their song "Lonely". B1A4 then held a solo concert, after which he took a role in "God's Gift - 14 Days". He plays a boy with intellectual disabilities. In the drama he's a boy in his late teens with a mental age of 6 years. His acting is very convincing, and is being well-received by viewers.

INFINITE's L is starring in both reality programs and dramas. On "This Is INFINITE", he's been expressing himself through his eyes and looks instead of using a lot of words, and proving himself to be quite influential in the group. In "Cunning Lady" he plays the role of a driver/assistant, and is bringing a youthful spirit to the drama.

L also brings a strong presence on stage with INFINITE members. The group recently concluded their encore concert for INFINITE's world tour, and L will be having a comeback with the group in April. They will be going into full-blown activities, and he will be a member of the unit group INFINITE F.

Singer Jung Joon Young made his name known from audition program "Superstar K3". Although they didn't formally form a group, Jung Joon Young has been working with winner Roy Kim, and became well known. He first introduced himself as a 'rocker', and his first album, which was released in 2013, was full of rock genre songs. But his songs weren't enough in making the singer popular.

However, once Jung Joon Young appeared on "We Got Married 4" and "1 Night 2 Days", Jung Joon Young's position has changed drastically. The formally chic and serious Jung Joon Young disappeared. On Saturdays he would greet the public as a spoiled younger husband, and on Sundays he played the youngest with his 4-D charm. This past February he started as an MC on "M Countdown".

ZE:A's Im Siwan has a completely different image onstage and his other activities. Singer Im Siwan has a childish face with immaculate skin, and is known as a sweet man. As he worked in his unit group ZE:A5, his visuals were highlighted even more. But his more impressive resume lies in his individual activities.

Im Siwan started acting in 2012 with the drama "Moon Embracing the Sun," and built up his acting resume. He then went on to work on a sitcom and even the mobile movie Misaeng Prequel. He was also highly praised for his role in the movie The Lawyer. He's also known for his role in entertainment program "Law of the Jungle," where he shows off his good looks and tough masculinity.
