The Trauma Code: Heroes on Call
I watched the drama first, and read the webtoon. They did change a few things, but it only to make the drama better (ex. the reason why Baek Kang Hyuk becomes a doctor in Hankuk Hospital, I shed TEARS on that one)
Overall, it was a fast-paced drama with a decent storyline and a great acting performance.
The only thing that bugs me is Park Gyeong-won's long hair doesn't look natural at all 😭😭😭
