I Became the Black Lotus Goddess

[Cheerful sweetheart x unconventional tsundere CEO] Zheng Ling dies in the apocalypse and transmigrates into a ridiculous domineering CEO novel she once read, becoming the story's cannon-fodder female supporting character. Before she can rise up, trample the scheming heroine, and punch the idiotic hero, the novel's villainous CEO drops from the sky and takes her under his wing. -When they first meet- CEO: “I hope things between us can stay pure. I only helped you because I appreciate how adorable you are. I hope you understand that our friendship is pure and untainted.” -Later- CEO: “Our friendship was never pure. I love you.” Why work in the office instead of the study? CEO: “If I wanted to work in the study, why would I come home from the company? I came back to see you. You're not in the study.” [Bonus scene] Vetting your suitor CEO: “If you're going to date someone, you have to let me vet them first!” (All right.) The CEO erupts in wounded fury: “What? You're dating someone, and it's not me!” Extra sweet.
