The cast of Lee Kyung Young always deter me from wanting to watch but he's literally everywhere. I paused for a while but eventually circled back to this but had to skipped 90% of his lines.
Then there's Cha Eun Jae's mom, I skipped her lines too. Control of a 30 year old is not something that's relatable to me.

S3 Positives:
-I loved the addition of the 2 new doctors that offered some comedy relief. Jang Dong Hwa & ex army doc Lee Seon Wung.
-They also kept most of the S2 cast including my favorite pair Cha Eun Jae & Seo Woo Jin. Hands down Seo Woo Jin is the best character.
-Master Kim evolved in this season to grand mentor status, no longer a hot head but super calm providing guidance.
-When the mentee becomes the mentor Seo Woo Jin character development.
-Relationship progressed with the couples as expected after 3 years.
-More screen time for veteran supporting cast Dr. Jung in Soo in all 3 seasons was very nice.
-Return of S1 Dr. Kang Dong Joo to the storyline felt nostalgic although he wasn't my favorite character in S1.

I hope this franchise can continue as there are so many interesting characters.
