For a special collaboration on this week's episode of 'Fantastic Duo 2', Red Velvet's Seulgi and Wendy joined up with the veteran singer Park Mi Kyung to perform "One Night Only".

The three singers took to the stage to sing the difficult song for the audience. They were able to perfectly execute the songs but also showed some dance moves to go along with it. The stage presence of the veteran singer mixed well with the talented and fresh styles of Red Velvet.
