This is my second time watching Park Shin Hye portray a doctor. The plot is actually quite good, and as someone in the medical field myself, I can understand some of the details in the series. The story follows Dr. Yoo Hye Jung, a tough and rebellious high school bully with a prickly personality. Due to her traumatic childhood, Hye Jung keeps her emotions locked away from others. Her character has great development, and after her grandmother's death, she decides to become a doctor, determined to investigate what went wrong with her grandmother’s surgery. This is one of the reasons she transferred hospitals. In terms of character writing, she stands out.

As for the romance, I think it could have worked, but not with the male lead, Professor Hong Ji Hong. I’ve watched a lot of series with significant age gaps, and while the age difference between them didn’t bother me, their chemistry did. It felt off, and I couldn't fully root for them. Part of the issue might be the writing; it was a bit unsettling at first. Teenage Hye Jung didn’t fall for her professor until she was an adult, but it seemed like the professor had feelings for her even when she was a teenager. Despite their relationship starting in adulthood, it was hard for me to support it knowing he was her former teacher.

I wasn't a fan of the professor's character either. Although the actor is talented and a veteran, his character felt stiff and uninteresting to me. On the other hand, Hye Jung had much better chemistry with her best friend Ji Soo or even the mafia guy she treated in the first episode.

Overall, I managed to finish the series, though it was painful at times, and I skipped quite a bit in the second half. While I might rewatch a few good scenes, I wouldn’t sit through the entire series again. The music, however, was quite soothing.
