"Good Doctor" Joo Won decides to become a messenger of love.

The 16th episode of the KBS drama "Good Doctor" featured Park Si On (Joo Won) becoming a messenger of love for Han Jin Wook (Kim Young Kwang) and Na In Young (Uhm Hyun Kyung).

Na In Hae (Kim Hyun Soo) is completely shocked when she learns that the person who will be donating her small intestines is her older sister Na In Young. She runs out of the hospital after being unable to deal with the shock.

Park Si On tells Na In Young, "In Hae must be angry and she is probably in a lot of pain right now but she will understand eventually. She has a big heart."

Park Si On continues, "Doctor Han Jin Wook really likes you a lot" and makes Na In Young hesitate. He continues, "He sleeps on the bed above me and every night he tosses and turns unable to sleep. I can't sleep because of the noise. So I end up staying up all night with him. I thought I was the most stupid person at this hospital but it turns out there is another person behind me. He is very, very stupid."

Park Si On adds, "Somebody once told me that there is no such thing as having a right to love somebody. If you love that person unconditionally, you naturally have the right to love them. I really wish you would give him the right to love you."
