It was reported earlier that Taeyeon would be performing a duet with Kim Bum Soo at his concert on November 23.  It appears that as a thank you gift, he had presented her with a pair of new earrings, which Taeyeon then showed off in a new Instagram picture!

On November 25, she wrote, "Given by Kim Bum Soo.. Today I sang, received a present, and my heart feels warm so I hope the people who heard the song also feel warm!" along with the hashtag "#Kim Bum Soo concert."
