With 2PM maxing out their Mutizen quota with Heartbeat after winning for the past 3 weeks, it was time to crown a new winner on Inkigayo. On the 20th December edition of Inkigayo, just three out of the seven Take 7 nominees performed - T-ara with Bo Peep Bo Peep, After School with Because of You, and K.Will with Miss, Miss, Miss. U-Kiss, f(x), IU and Park Jin Young did not perform. And after making their debut earlier in the 2009, After School managed to sign off the year with a flourish by claiming their first-ever Mutizen and major award for Because of You. It was already highly anticipated since the song had been charting at No.1 on various charts and ran 2PM close on Music Bank a few days ago. And it was no wonder that Kahi and the girls got emotional as they teared. Congratulations to the After School girls who has had to say goodbye to Soyoung and welcome new members UEE, Nana and Raina to their ranks in less than a year.
