Why did I not see this special stage before?!
Anyway. It's such an adorable performance, especially since 2AM and Beast are good friends with each other :)). The solo parts are all raps, so it's cute seeing all the non-rappers rapping haha XD. Needless to say, Doojoon and Junhyung did the best, but the rest did a decent job too! Kikwang's part is just so cute; I don't even know why HAHA. Jokwon is SUCH a good dancer. It's quite a pity that he isn't in a dance group.
If you listen closely to the chorus, you can totally tell when Yoseob was singing and when he wasn't. Because when he was, there would be one very stable, clear voice which stood out, and when he wasn't, it would just sound like a few voices singing together. And I'm NOT just saying this because he's my bias. Plus he was sick that day! I had a feeling that he was when watching this performance, since he kept looking down and after his solo part he was panting so hard. And I confirmed it after watching Beast's performance on that day. If people were to watch only the special stage, they wouldn't be able to tell that he was sick.
Okay so anyway. 2AM+Beast rock :D.
