A Cold, Ruthless, Calculating and kind of a jerk MMC, and a FMC who is in love with the MMC (before the MMC falls for her) and is very patient and forgiving towards him.

I need a romance between a MMC who is very cold (not socially awkward, could charm if he wanted to but just isn't interested in most people), ruthless, very calculating and scheming, and a bit of a jerk (could depend on perspective, I don't necessarily need him to keep throwing slangs and insult people out of spite). And in pair with him is a FMC who is (for whatever reason) in love with him, before he has even any modicum of feelings for her, and because of this she is very patient with him, forgives him if he ever hurts her in some way (maybe not immediately, but eventually because she can't stay mad at him for too long).
