D.O and Jo Jung Suk will sing the ending track for the film, Hyung Reuters

Fans of D.O. and Jo Jung Suk are in for a treat. The duo sang the ending song for their upcoming film, Hyung.

The music video for the ending track titled, Don't Worry, My Dear, is set to release on 24 November.

"I thought there would be more synergy if we sang the final song together. Because Jo Jung Suk is a really great singer, I always thought it would be good for us to sing together," D.O. said.

Jung Suk added: "We really sang the song as our characters Du Young and Du Sik, instead of singing the song as D.O. and Jo Jung Suk. Words cannot describe how good of an experience it was."

Previously, the leading characters had talked about their roles in the movie. Jung Suk said about his character Go Doo Sik: "You must realize after watching the trailer, but I'm a horrible swindler with 10 violations of the law on my criminal record from fraud. This isn't like my actual personality, so I had a hard time while filming."

He continued: "There's a significant age difference between Go Doo Sik and his younger brother Doo Young. I try to sell my younger brother to get rich, but it doesn't work out in my favor so it was fun."

D.O, who plays his younger brother Go Doo Young, said: "I'm the popular national team athlete Go Doo Young. On the outside, I seem strong and proud, but on the inside, I have a soft and innocent side. [Go Doo Young] is a little bit like the real me."

D.O. and Jo Jung Suk's film is set to premiere on 23 November.
