B1A4's Sandeul has successfully taken his first step as a musical actor by completing his first performance at the press call stage for his musical, 'Brothers Were Brave'.

Although he had a few parts, the main vocalist demonstrated that he was as determined as ever by showing his absolute best for each song. Sandeul plays the role of 'Lee Joo Bong', the second son of the leading role, and is triple cast with musical actors Sung Doo Sub and Jo Kang Hyun.

According to officials, Sandeul's actually suffering from an eye infection and isn't in the greatest condition to be performing, especially since B1A4 only recently completed their album promotions. Despite this, Sandeul showed his potential as a budding musical star by successfully completing each stage and staying behind to greet each actor.

The musical will run from June 26th through October 1st.
