In "Cantabile Tomorrow," Joo Won started to get jealous of Park Bo Gum and Shim Eun Kyung's relationship.
On the episode of KBS2 Monday/Tuesday drama "Cantabile Tomorrow" broadcast on November 4th, Yoo Jin (played by Joo Won) saw the picture that Sul Nae Il (played by Shim Eun Kyung) and Lee Yoon Hoo (played by Park Bo Gum) took together and showed a bit of jealousy.
Seeing Yoo Jin's performance, Nae Il didn't contact her friends for a couple days and only focused on her piano performance. Afterwards, she met with Yoon Hoo, Min Hee (played by Do Hee), Il Rak (played by Go Gung Pyo) and felt happy. Yoon Hoo said that he'd buy a snack for all of them and they moved to another place.
With this, Nae Il took a picture of the food that Yoon Hoo had bought and took a selfie. She then uploaded it onto her social media site, which upset Yoo Jin.
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.
