OMG ! Thunder ! you made me so touched ^^
I'm a Cassie, and I love MBLAQ, when I saw this on HB, I actually got so emotional I started to cry ;; It makes me happy ... that DBSK are remembered

Awww~ This is one of the moments when I'm mega proud to be Cassie.. Too bad the lil girl doesn't like Thunder when he sings it.. XD
