^ LOL I can only recognize some of them!
Sungmin & Kyuhyun (wearing glasses) on the top left.
Kangin & Eeteuk (with the angel wing on his shirt)
Shindong on the very top
Yesung & Ryeowook on the top right.
Heechul on the floor with red hair (?)
Is Kibum the one under the tree?
I can't find:
Donghae (bottom left? near Eunhyuk?)
Eunhyuk
Hankyung (near Heechul?)
Siwon (in the middle looking at Kibum - under the tree?)
I'm so horrible
