IU and MBLAQ delivered a perfect performance of Rain's "Rainism."

On the 6th of July, a special episode of KBS "Music Bank - Hong Kong," featured idol stars IU and MBLAQ, who delivered an impressive performance to the song "Rainism" by Rain.

Recently, IU performed to one of Rain's songs at her own concert. Although IU seemed to be a little uncomfortable during the performance on "Music Bank," she looked adorable regardless. On the other hand, MBLAQ members have taken on the title of "Rain's successors" and have prior experience performing to Rain's hit songs. Ever since their debut, MBLAQ members proved themselves to be deserving of the title "Rain's Successors" with their powerful and flawless performances.

The collaboration performance of IU and MBLAQ instantly took Hong Kong fans' breaths away. The biggest factor of their successful performance was how synchronized IU and MBLAQ were while performing their sexy dance moves as well as their passionate glances in each other's eyes.
