It will be good to see KARA-DBSK but i think it's not goin to be possible. Anyway, i'm looking forward for more collaborations between these couples:
1. Jiyoung + Nickkhun = MATCHING COUPLE, their height and face just fit each other so much
2. Jiyoung + HongKi = CUTE & LOVELY couple...especially how Hongki is so caring for Jjing
3. SS501 + KARA
