I recommend the novel "The Killer's Wife Is A Little Sweet" to you. The male protagonist is the world's number one female killer. He was reborn into an ugly and cowardly female student and married a sickly demon from hell. The Queen attacked aggressively, tearing apart the white lotus with her hands and stepping on the dregs with her feet, subverting the conventional image. The male protagonist drives a Grand Cherokee, while the female protagonist is a student. Both of them meet your requirements. I hope you like my recommendation, Mwah ~😗
