Excellent medical / investigation drama, set in an unusual setting: that of a dilapidated hospital on Zal Island, with few resources, few staff and a poorly educated population to treat.

The plot follows a team of Chinese caregivers who come for 2 years to help local hospital staff.
The topics covered are of course classic in a med-drama (life, death, suffering, family/caregiver decisions, cost and financing of care, etc.) but also epidemics, viruses, drug research, clinical experimentation,...

The actors are excellent, all of them! The CL is very endearing (I have become a fan of TonyYang ❤❤❤, his casual, charming character,... is just too cute) and their interactions are too rare, because their chemistry makes you want to have more intimate moments together on screen.
But the secondary characters are well developed and skillfully played. The psychology of the characters is coherent, subtle. We are attached to this team of caregivers whose cohesion, support, friendship, are the pillars in the face of the disease.
There is no real evil character, perverse or Machiavellian, because even the "great villain" have credible motivations.

The production is neat, quite dynamic and the images are beautiful. They make you want to discover this isolated island.
Nothing special on the OST.

I highly recommend this drama, which I will probably rewatch.
