110812 SuJu 11th Floor - I Yah @ Kiss The Radio

[cr: 내꺼해 @ SJ-Market] SuJu 11th Floor = Kyuhyun Sungmin Yesung Eunhyuk because they all lived on the 11th floor XD and they had a battle with 12th floor (HaeTeukRyeoDong) IYah is originally by . and was one of the best hit of them! Yesung is so funny, he ran out of breathe at the end singing so everybody laughed so hard XD
