Earlier this year, news outlet Herald POP, reported that the members had been discussing a possible comeback. At the time, Jo Kwon‘s agency Cube Entertainment said in a statement that the reunion was “being reviewed positively.”

Im Seulong‘s agency Jellyfish Entertainment and Jeong Jinwoon‘s agency Mystic Story had also supported the claim, saying that they were also considering a possible reunion of the beloved vocal group.

2AM – comprised of Jo Kwon, Lee Changmin, Lim Seulong and Jeong Jinwoon – made their debut in 2008, as a sibling group of boyband 2PM. Over their seven-year career, the vocal group released four studio albums and three mini-albums before going on hiatus in 2015 after three of the four members left JYP Entertainment.
