Kim Jun-su of JYJ performed the soundtrack of “Descendants of the Sun” for the first time on Wednesday at his concert in Tokyo.

During the concert, Kim became a genie making fans’ three wishes come true. For one of the wishes, a Japanese fan asked him to give a live performance of the drama’s soundtrack.

“It’s the most popular drama in Korea. I participated in singing the original soundtrack,” Kim said. “The song was featured in the drama but hasn’t been released yet. But I am surprised that my Japanese fans know about it. This is the first time to perform the song live,” Kim said and sang parts of the song.
