I remember the chapter in the On or Off where director Kang was a student and in relationship with an older woman. And he was sad because he broke up with his girlfriend. His girlfriend went to Paris and wanted to break up because he was young and didn't ask him to wait for her. Director Kang was ready to wait for her because he believed in the forever love. Now Yiyoung is like director Kang when he was a student. He believes in ending from your first relationship to living together forever. It's not that Director Kang doesn't love him. He loves him very much that's why he thinks he is holding Yiyoung back.
