?

I watched the first episode and I was confused. Then I watched the second one and I am still confused about what is going on that nurse acts like a mentally ill person but she's not?????? What in the world is this drama, istg ??? hopefully in the next episode things star making more sense. Idk how they gonna do it since it only has 6 eps, but they better do it. I started watching because it looked interesting, but turns out it's just pure madness until now.
