2AM is a four member boy band signed to JYP Entertainment. They are one of the two subgroups from the 11 members band, ‘One Day‘ (The other being 2PM), and unlike their brother group they mostly sing ballads and love songs. They debuted in 2008 with their single “This Song“, but it wasn’t until 2010 that they rose in popularity and won their first #1 award for their song “Can’t Let You Go Even If I Die“ on Inkigayo. Aside from their singing the boys are known for their roles in various variety shows. Although most people would think that the boys would be calm and reserved since they are known for their powerful love ballads, 2AM are one of the craziest and rambunctious idols in the KPOP industry.
