First, the worst ending I've seen without a doubt, 40 episodes for something so stupid and boring?
The drama was very bad after chapter 30, they no longer knew what to do, and they were adding deaths, sick of any kind, without need.
When the 30 episodes passed, they should have given it a closure and not lengthen it with more patients and cases, and the return of the girl who was unilaterally in love, should not have returned and should not have left and so the protagonist would have told her what he said near the end.
Some cases they dealt with were really well done, but they were many and unnecessary, after chapter 31 I went ahead to only get to episode 40, and the truth is I should have done it sooner, since I didn't like the ending!
The romance came to nothing because it didn't even exist, they shouldn't have classified it that way.
The chemistry between the leads was good, the supporting characters were very annoying with their gossip, etc.

In short, for having more than 30 chapters and such a poor ending, I give it a 6 out of 10.
