Hyoyeon and Kwanghee's passionate couple tango dance is becoming an issue.

In SBS "Star King" aired today, Girls' Generation (SNSD) Hyoyeon and ZE:A Kwanghee showed a couple tango dance.

On this day, they wanted to show the scene from the movie 'The Woman's Scent.' Kwanghee showed moves full of energy unlike the silly image he usually has.

Internet users who saw this commented, "It was fun to watch," "It was so passionate," "The two look good together," and "Han Sunhwa, are you watching this?"
