KBS Monday/Tuesday drama "Cantabile Tomorrow" Shin Eun Kyung and Joo Won are filling up the drama set with a lot of expectations.

On October 29th, the staff of KBS Monday/Tuesday drama "Cantabile Tomorrow" (script Park Pil Joo, Shin Hae Won, director Han Sang Woo, Lee Jung Mi) released behind the scenes cut of Joo Won and Shim Eun Kyung who are exploding with chemistry as if drawing out others' jealousy. They are always together, even when they're waiting to be on set, and taking care of each other like a true couple.

Shim Eun Kyung was putting on clothes on her pet dog. Seeing her, Joo Won must've thought that Shim Eun Kyung was cute. He walks over and at some point, he starts to pet her hair and show a nicer side. Because of this, the two overcome what would otherwise be a bit more embarrassing physical touching situation. They accordingly showed off perfect chemistry.

Meanwhile, "Cantabile Tomorrow" is a KBS2 Monday/Tuesday drama adapted from the Japanese manga with the same title. In the drama, Yoo Jin (played by Joo Won) is a piano major with a world famous pianist father who is not only attractive but has exceptional music talent. However, his father cannot ride in a plane or boat because of childhood trauma and such limits his future opportunities.
