2PM is a South Korean boy band formed by JYP Entertainment in 2008 composed of six members: Jun. K, Nichkhun, Taecyeon, Wooyoung, Junho, and Chansung. 2PM was originally a seven-piece group; Jaebeom left the band in 2009. Unlike most Korean boy bands at the time, 2PM constructed a tough and masculine image through their intense performances often featuring acrobatic stunts and sex appeal. As a result, 2PM is known for creating the "beast idol" phenomenon within South Korea. As the group grew older, they stopped incorporating acrobatics in their choreography routines and transitioned into a more gentlemanly image. The group has achieved commercial success in several regions in Asia, including South Korea, Japan, and Thailand, as a leading figure of the Korean Wave. 2PM debuted with the song "10 Out of 10" on September 4, 2008. They achieved their first number-one single with "Again & Again" in 2009, which contributed to them winning the 2009 MAMA Award for Artist of the Year. Both singles, along with their hit song "Heartbeat", were featured on their debut studio album, 01:59PM, which topped the first issue of the Gaon Album Chart.
