Criminal Daddy - Villain Daddies, #11

A normal couple goes on dates, gives each other lovely gifts, and thinks about buying a house when they get married. Lucas and Lottie are just about as normal as they can get. He spoils her. He corrects the mistakes that she makes when she improperly disposes of a corpse. He sternly says one thing, but his heart is looking out for her, and he takes on dangerous jobs to take care of her. He doesn't mind crushing what little pride he had as a former military man to be the cold-blooded criminal to make her happy. This new job has higher stakes, but he's not a coward. She, on the other hand, is a weakling.
What else can he do other than to look out for her? Not that he minds.
