Yoo Seung Woo sang a sweet serenade for Girls’ Generation’s Sunny.

The young singer appeared as guest on the October 5th episode of ‘Quiz to Change the World’ and performed Girls’ Generation’s “Genie” in his trademark acoustic style for Sunny who served as a special MC.

Kim Jong Jin praised him by saying, “Yoo Seung Woo is a guitar genius. The chords that he is using are very tricky, so they’re not used often. Not as many people can manage it so smoothly as he does. At first I wasn’t so sure, but the more I listened, I started falling into his charms.”

Watch his performance starts at 14:55.
