September 10, the 12th episode of the KBS drama "Good Doctor" featured Park Si On (Joo Won) finally telling Cha Yoon Seo (Moon Chae Won) that he likes her.

During this episode, Park Si On is emotionally hurt after training with Kim Do Han (Joo Sang Wook). When Cha Yoon Seo sees him feeling down, she tries to cheer him up. However, Park Si On avoids her because he becomes extremely ashamed for not being able to impress her.

Eventually, Park Si On says, "I don't want you to see the embarrassing side of me... because I like you. I get the hiccups and my heart starts beating so fast. I don't want to look stupid in front of somebody I like. I want to be confident and brag but it's not as easy."

Later on while Park Si On is walking home, he gets attacked by several people. Ki Do Han appears and saves him. Park Si On makes up his mind of forget about his feelings right then and there. He says, "I think I need a lot more licenses to do more things. If I have a lot of licenses, there is nothing you can do. I want to walk alone" and leaves.
