No, Bro... You just not understand with the storyline... I suggest you to rewatch from first episode and watch it with high focus. You will see how dark this story will like.
I don't remember much of S2 what's this Oddball project?????????
I think you can remember about it if you remember about a such thick file that was started by Yun Dong-ju and our Dr. Romantic in S1... After that in S2, there some doctor and nurse helping to update that file together with our Dr. Romantic... (honestly, I was watch S1 and S2 about 3 years ago in Covid outbreak... so I wrote by what I remember. Sorry if thare was some mistake...)
