Kang Byung Sun, known previously as Siyoon and currently as Sun, is a South Korean singer, dancer, former member of A-PRINCE and current member of MAP6. Before debuting, he spent time as a trainee at DSP Media and was one of the candidates to join A-JAX but he was not chosen in the end. After switching companies, he debuted in 2012 (under the stage name Siyoon) as A-PRINCE's vocalist and main dancer with the song "You’re The Only One". The group had previously debuted as TAKEN in 2011 with the single "Only You" but they were not very successful. One year later, they decided to re-brand as A-PRINCE and added him as a new member. In 2015, the agency New Planet Entertainment, held talk with the members and opted to disband the group. He remained in the company and re-debuted as a member of MAP6 in 2015 with the single "Storm". The group released several singles and one full album but has never enjoyed a huge success like other groups. In late 2019, it was announced that MAP6 will go on hiatus as 4 of the 5 members were getting ready for their mandatory military service. All of the members have been discharged but the group has not gotten back together suggesting it quietly disbanded.
