Legacy of Ra.D

2PM (Korean: 투피엠) is a South Korean boy band formed by JYP Entertainment in 2008 composed of six members: Jun. K, Nichkhun, Taecyeon, Wooyoung, Junho, and Chansung. 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 jimseung-dol 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.

Son Ga-in, known mononymously as Gain, is a South Korean singer, actress and entertainer, best known as a member of the South Korean girl group Brown Eyed Girls. Having debuted with her home group earlier in 2006, Gain eventually made her solo debut in October 2010 with Step 2/4 to great commercial success, and has since released a total of six extended plays. In addition to her musical career, the singer also appeared in several native programs and series, most notably We Got Married and All My Love for You, where she co-starred alongside 2AM's Jo Kwon.
