"Good Doctor" Joo Won continues to grow and mature.

October 1, the 18th episode of the KBS drama "Good Doctor" featured a patient's guardian learning about the fact that Park Si On (Joo Won) was previously diagnosed with a mental disability. The guardian states, "I cannot leave my child in the hands of someone like that."

However, the guardians of other patients who have all been treated by Park Si On state, "That doctor has no problems at all. He is extremely detailed and we love him." Regardless, the guardian refuses to listen. Park Si On says, "I'll have a different doctor assigned to you. The doctor should be chosen by the guardian."

When Cha Yoon Seo (Moon Chae Won) worries about him, Park Si On tells her "I'm really okay" and acts perfectly fine. Kim Do Han (Joo Sang Wook) also tells Cha Yoon Seo, "Park Si On accepts himself for who he is now. You don't have to worry anymore."

Kim Do Han continues, "What is more amazing is that Park Si On's genius abilities have become meaningless now. Before, he didn't have anything other than his genius abilities but now he has a lot more going on for him. Even without his special abilities, he will be able to become a highly respected doctor."
