Dr. Romantic 3 primarily revolves around the clash of ideologies between two main characters. The first ideology is embodied by Kim Sabu, who represents an idealistic style of thinking. The second ideology is portrayed by Prof. Cha Jinman, who embodies a realistic style of thinking. While some may not agree, Prof. Cha Jinman was undoubtedly one of the main characters throughout the show.

In the last four episodes, we witnessed intense clashes of opinions between Kang Dongju & Cha Eunjae + Seo Woojin.

Neither Kim Sabu's idealistic thinking nor Prof. Cha Jinman's realistic thinking seemed perfect to me.

However, I found myself partially leaning towards Prof. Cha Jinman's realistic approach. From my perspective, he wasn't the villain that many people made him out to be (I know actor's controversial past but here I am only talking from character's perspective).
I appreciated how he shed light on the challenges doctors face due to angry patients & their families. In the end, doctors are human too & they deserve respect. While he wasn't entirely right, his realistic mindset resonated with me more compared to Kim Sabu's idealistic approach.

In terms of romance there wasn't much development. The main couple's romance seemed stagnant although they started living together but unfortunately, FL's family created unnecessary obstacles that hindered their progress.
The second couple had a smooth relationship until an unnecessary breakup trope was introduced. Frankly, the reason for their breakup seemed quite childish to me.

The cases featured in Dr. Romantic 3 were engaging & intriguing. Personally, I found the cases in Season 3 more interesting compared to those in Seasons 1&2.
Specially, collapsing building case & fire at the chemical plant were the most captivating to me.

Overall, I enjoyed Dr. Romantic 3 more than its predecessors because the cases in this season intrigued me the most.
