In "Cantabile Tomorrow," Shim Eun Kyung started to misunderstand the relationship between Joo Won and Kim Yoo Mi.
On the episode of KBS2 Monday/Tuesday drama "Cantabile Tomorrow" broadcast on November 4th, Sul Nae Il (played by Shim Eun Kyung) finished her performance and ran into Yoo Jin (played by Joo Won) who was standing in the photo zone.
Yoo Jin had become a star with his perfect performance and took a picture in front of the reporters after finishing his performance. In this process, Yoo Jin's mother Sun Young (played by Lee Ah Hyun) and ex-girlfriend Do Kyung (played by Kim Yoo Mi) were standing together as well. The reporters said amongst themselves, "They're so good looking." In between all of them were Nae Il and Min Hee (played by Do Hee).
Min Hee realized that Sun Young was Yoo Jin's mother and because of this, Nae Il was shocked. To Nae Il, he said, "You're just going to be humiliated. I think it's because Yoo Jin is the president's son. Do you know how coy Do Kyung was?"
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.
