Summary
→ Summary: F1 driver Vernon is no stranger to stunning women whispering wicked things in his ear during race season, but no voice has stopped his heart quite like yours. The ‘missing’ younger sister of one of his oldest friends. The girl who disappeared two years ago without a word. And now, you’re on his lap with your bare breasts pressed against his chest. He’s horrified to learn that you’re working at an exclusive strip club, tangled in a complicated contract where sex appeal is currency, personal relationships are forbidden, and your freedom is nothing but a twisted illusion. He wants you out, but walking away from a fantasy life built on status and money isn’t that simple. So, in a last-ditch effort, he offers you something else. Something real. A fresh start on the circuit as his assistant, where you can rebuild your future, possibly even a future by his side.

→ Summary: In a dark, pulsing nightclub packed with strangers, you’re just looking for a good time—free drinks, dirty dancing, maybe a hot kiss or two. But when Mingyu finds you on the dance floor, he changes the game entirely. What starts as harmless teasing spirals into a filthy, no-boundaries encounter right there in the crowd. And by the end of it, you're not sure who’s corrupting who.

Summary
→ Summary: Still nursing the sting of his Lupercalia heartbreak, Yeosang finds unexpected solace in you, his friend, classmate, and favorite co-conspirator. What starts as playful companionship shifts the night he helps you bind a particularly wicked hex. Something changes. Suddenly, he doesn’t view you as just a friend. And he’s done pretending otherwise.

→ Author Note: This takes place after Disgraceful Dreams, consider this a follow up with Yeosang’s story. If you haven’t read that fic, I def recommend doing so before reading this! This fic takes place the following spring, and y/n from DD is also named Lia in this fic to keep things less complicated. Once again, the specifics relating to Ostara are stretched to fit this fic. All kudos and comments are appreciated!
