The love triangle between Joo Won, Shim Eun Kyung, and Park Bo Gum began.

On the 6th episode of KBS Monday/Tuesday drama "Cantabile Tomorrow" (script Park Pil Joo, Shin Jae Won, director Han Sang Woo, Lee Jung Mi) broadcast on October 28th, Lee Yoon Ho (played by Park Bo Gum) rescued Cha Yoo Jin (played by Joo Won) who had fallen into the water as a swimming pool of a water park.

Afterwards, they reunited at the Yoon Yi Song music festival. Sul Nae Il looked from far away as Cha Yoo Jin practiced her music. To look more carefully, he went up to the street lamp. Lee Yoon Hoo found Sul Nae Il trying to do this and the two met again.

Sul Nae Il said to Lee Yoon Hoo, "Please let me see him." Then, Yoon Hoo agreed as he went to the place where France Shrootrejeman and Cha Yoo Jin were. As soon as Cha Yoo Jin saw Lee Yoon Hoo, he said, "Are you a koala? Come out now."

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.
