Indicating the desired collaboration between the Korean Boy Band "2PM" and the Korean girl band "After School". 2PM was widely called the beastly idols in Korea because of their fiercely sexy image. 2PM had sang and danced to every After School songs, including Ah (at the program Idol Army), Diva (at the programs Wild Bunny and M Countdown), Because of You (at the program Ingigayo/Music Trend), Bang (at the program Dream Team) and Magic Girl (at 2PM First Concert)
Meanwhile, 2PM called After School "the female beast idol" (see SBS radio show 'Heechul's Young Street') and the girls danced to two of the 2PM's songs 'Again and Again' (at the program MBC Star Dance Battle) and Heartbeat (at SBS Gayo Daejun).
Since their style is so similar, many fans of both groups wanted a formal collaboration and joint stage of the two groups in the future.
A: See! It's 9PM (2PM with another Korean cutie girl group SNSD/Girl's Generation) performance.
B: Oh! Come on! The two groups have so different style! After2PM would be so much better!!
