"Good Doctor" Joo Won begins to hallucinate.

September 9, the 11th episode of the KBS drama "Good Doctor" featured Cha Yoon Seo's (Moon Chae Won) touch making Park Si On (Joo Won) incredibly nervous.

During this episode, Cha Yoon Seo hugs Park Si On and says, "You did an amazing thing!" Park Si On hesitates when his heart starts to beat uncontrollably and leaves the room right away. He takes deep breaths to calm himself down once he escapes the room.

In Hae (Kim Hyun Soo), Park Si On's dating coach arrives right then and says, "You're acting like this again. What are we going to do with this burning desire of yours? Dress up looking clean and get a rose. You need to confess your love. If you keep it in, it's going to become worthless."

When Park Si On says that he is too afraid, In Hae says, "Do it whether it works out or not!" When Park Si On says that he is afraid that his secret admirer might not like him, In Hae says, "Tell me who it is. That's the only way I could coach you according to the circumstances."

Park Si Won is embarrassed and says he will write it on a notepad and show it to In Hae. However, instead of writing Cha Yoon Seo's name, he writes "Not going to tell."
