Idol group Super Junior's member Sungmin and the musical actress Kim Sa Eun are dating.

According to one media, a witness said, "The two had visited LG Art Center in order to watch the musical 'Prisciplla' on July 18 and they were with a woman in her 40s at the time."

The witness said, "Sungmin had a hat on and seemed nervous trying to cover himself every time someone was passing by but they were in a relationship without a doubt."

Their past pictures on Twitter also caught much attention. The two were wearing couple rings and bracelets.

The two had worked together for the musical "The Three Musketeers" last year.

On this day, both agencies of Sungmin and Kim Sa Eun admitted that the scandal is true.
