I know they are in practically every drama, but please give me drama where you remember it happened. You can give spoilers, I don't mind.
1. The FL is seriously injured because she has protected ML (has been stabbed, shot, or injured in some other way). ML is of course worried. I watched: Melting me softly, legend of blue sea, vincenzo, mr queen, Crash Landing on you and a few others.
2. FL is injured (it can be a minor injury, it could be a simple ankle sprain, burn, a small knife cut ... just minor wounds. Most importantly, ML should be worried and take her to the hospital or "treat" her by himself)
3. FL (human) falls in love with a supernatural being. I watched Goblin, My roomate is Gumiho, Tales of the Ninetailed, Scripting your destiny and a few more.
4. FL falls in love with ML who is older than she is. I watched a lot and I want to watch more XD..Ideally, ML should not be interested in FL at the beginning.
5. FL falls in love with ML, but he rejects her, then she tries to fall out of love with him ... and he falls in love with her. They end up being together.
It can be Cdrama, Tdrama, Jdrama too
