Hyoyeon of Girls' Generation shared a moving moment from Seohyun's performance.
On the 15th, Hyoyeon posted several photos on her Instagram with the caption "Reunited with Your World."
The photos show Seohyun, who joined as a special guest soloist at the 'Sol Philharmonic Orchestra 8th Regular Concert' held on the afternoon of the 13th at Lotte Concert Hall in Songpa-gu, Seoul.
Hyoyeon also posed affectionately with Seohyun, showing off their 'real friendship'.
Meanwhile, the concert drew attention because Seohyun had only been learning the violin for about five months. Ahead of the show, some criticized an amateur celebrity taking a stage even professional performers struggle to secure, sparking a 'privilege' controversy.
