Looking for a c- och k-drama with the male lead really sick, or hurt a lot. Preferably so he is staying a lot in hospital.  NOT psychologically, so no depression and so on if it is not a symptom of his real sickness/injury.
It could also be historical but preferably modern.
What other genre does not matter, the important is that the male lead is really sick or injured.
If he is normally a strong character that is even better but ok if he is weak to.

They're historical, so no hospital, but 

The ML of Love In Between was poisoned as a child and is sick/weak for the entire drama. 

Legend of Fei has a ML who was poisoned and is sick/weak for the second half of the drama.

Listening Snow Tower has a ML who is very ill with a cold sickness. He's still very strong/powerful despite this.
