The two performed together a duet, which you can watch above.  Afterwards, she was asked how she felt getting to perform with Kangta, and she said, "Honestly, I've always been a fan of Kangta.  I was [an early member] of the H.O.T [fan] club.  Even yesterday, I listened to [his radio] live and sent in a situation."

Kangta said, "When I received letters from fans while under H.O.T, there were many stating, 'I will become a singer when older,' or, 'I'll be a writer,' and Younha truly became a singer-songwriter and a colleague," unable to hide his happiness.
