With only a few weeks before the drama's release, actors Joo Won and Shim Eun Kyung are giving their all for their upcoming romantic-comedy "Tomorrow Cantabile."

On September 30, some behind-the-scenes photos of Joo Won playing the piano were released, showing the actor working hard while he is practicing.

As his character Cha Yoo Jin is known as a perfectionist with whatever he does, Joo Won is training hard to learn how to play the piano and violin like a professional.

In the photo, Joo Won can be seen wearing Cha Yoon Jin's trademark black and white ensemble, and serious expression. Standing next to a grand piano, Joo Won looks like he belongs in the classical music world, showing that he was the right choice for the role of the genius aspiring conductor.

Meanwhile, Shim Eun Kyung is also doing her best as the titular character Seol Nae Il, as shown in the photo that she posted of herself practicing how to play the piano.

On September 29, the actress uploaded a photo along with the caption, "I really like the piano. Someone took this photo of me while I was practicing. More than acting well, I also want everyone to see how much I'm enjoying what I'm doing. I want to thank all the fans who have been monitoring my activities. You all give me a big boost of strength!"

Shim Eun Kyung's character Seol Nae Il is a free spirit when it comes to playing the piano, and it seems that she is taking the right approach to her portrayal by channelling her character and enjoying the piano.

"Tomorrow Cantabile" is a romantic-comedy that follows young musicians on their journey to reaching their dreams of becoming professionals in the field of music.

KBS's "Tomorrow Cantabile" will be broadcast every Mondays and Tuesdays starting on October 13.
