For those of 당신 who have no idea who No Min Hyuk is, here's a little information. Click-B is an ex-idol group from DSP Entertainment. They had seven members and they were very active and 인기 in the late 90's and early 2000's. No Min Hyuk played the 기타 in the group and is now part of another group called AshGrave.
After hearing him sing and play the guitar, the singer gave him a round of applause for his exceptional talent. Taeyeon expressed that she had always wanted to learn how to play the 기타 so she asked her listeners for 조언 on who she should hire as a 기타 tutor. Even the radio listeners recommended No Min Hyuk.
Taeyeon then asked him for some lessons on guitar-playing. In the end however, she had to take back her request because of her packed schedule: an Asia 음악회, 콘서트 tour, a radio show and year-end award shows.
