I just had to share this with you all because this is so much perfection in 2 and a half minute.
If you've read my story "A Fangirl's Heart," you see how I reaaaaaaally love the friendship between Woo Hyun and Key, and DongWoo and Xiu Min. And nooww... They're all performing together!!!!! This is sooo cute! It's like the 4 best friends performing together. (If you didn't know, Dongwoo and Xiumin used to be schoolmates, and they're both 90liners). You can see how they're all having fun and enjoying the performance too. I also love how they're sort of divided like a battle between SM vs Woollim to win the girl. XD 

And it's not often we can see Xiumin wearing such eccentric clothes. I'm used to seeing them on Key, but seeing it on Xiumin gives it a different feel. As for Dongwoo, does anyone thing his pants is slightly weird? I mean, if it's all purple, then keep it purple.. Don't add a random yellow part... there... LOL.. And Woohyun? PERFECT!!!!!! Hehehehehehe..
