Mmkay. This has got to be hands down my favourite performances of Hello ;) Why?
Starting with the fact that they used Love Pain for the intro. Omg. That song is amazing :')

1. The fanchats from 0:17 - 0:24 were so loud & awesome <3
2. The little gesture Onew does from 0:42 gets me every time, and his smile ><
3. 0:46, OnHo's couple dance was tooooo cute! It made me smile so wide because they looked like they were enjoying it so much <3 
4. 0:51, Jonghyun's flying kiss. Need I say more?
5. Key ruffles the hair on the back of his head at 0:58 and drives the fans wild ;)
6. 1:13, Taemin's little popping move was soooo epic. *_*
7. 1:18, "MINHO!" fans are daebak. it's only for his part that they do this, right? <3 Minho appreciation everyone <3 
8. 1:41, JongKey's couple dance. <3 They could've done better, OnHo seemed to have enjoyed it more (but we call know JongKey is real haha)
9. 1:52 - Jonghyun's 'V', 1:56 - Key's 'V' AND wink. Was he trying to outdo Jjong? xD
10. 2:00... najcklskv. Taemin. WAE. SO CUTE. HIS HEART. OMG. <3

13. Minho aced his part at 2:31 ;)
14. 2:46... that hip move. So in sync. I could stare... forever *o*
15. 2:55/56. Did Onew's voice crack... again? xDDD
