Veteran singer Insooni has released a new performance video featuring a very surprising face!

On December 25 KST, the singer unveiled a new installment of her 'IN&LIVE' video series. While in the past, 'IN&LIVE' has largely featured Insooni performing cover songs, this time around, she teams up with N.Flying's Yoo Hwe Seung to perform the duet version of her 2019 single "Happy."

The video starts with a special message from Insooni, who confessed she had thought over which performance she would like to gift everyone for Christmas this year. She then decided on this video, which she and Yoo Hwe Seung had recorded together in 2019. She hopes that, just like the song's title, her fans can enjoy a happier and warmer end of the year.

Meanwhile, on top of his activites with N.Flying, Yoo Hwe Seung has spent 2020 in a number of solo projects, including appearing on 'Immortal Song' and releasing an OST single for 'The Spy Who Loved Me.'
