Sudden Love dramas

A list about shows which feature unwanted love. 

What is unwanted love? Attraction to someone without wanting to be attracted to them or not understanding why. Could also be defined as illogical love. The attraction has to be resisted at some point or at least not acknowledged. It's very specific so I'm trying to list all series I can find with it.  

Only series with heavy focus on unwanted love of one of the ML will make it on the list. The ML has to show some resistance to the idea of falling in love. 

 Crossdressing series and some BL feature this trope heavily but they will not be included.
