Please recommend dramatic romance dramas where the ML falls hard for the FL (or other ML, if it's a BL), and is willing to make big sacrifices for her. Ideally, the kind of drama where he's willing to kill to protect her if he has to, and where he's also willing to put his life on the line (and even die for her) to protect her.
Preferably also dramas where the ML isn't a jerk to the FL for most of the drama. Being a jerk at the beginning isn't a deal breaker if he gets compelling character development.
If you can, please include a warning if there's super minimal skinship (like Mr. Sunshine).
I mainly watch C Dramas and K Dramas, but I'm interested in recs from any country.
