Any romance dramas where the FL tries to kill the ML but the ML is so head over heals for her that he completely forgives her / ignores the attempted murder / worries about her instead of himself?
Empress Ki - but I think you already watched it. ML is completely head over heels for FL to the point where he is fine being used for revenge. There is a scene where she actually attempted to kill him but I don't think he was aware of it.
