Sinful Enemy

A drunken wedding forces sworn enemies to play newlyweds until fake turns dangerously real.
Kate wakes up with a pounding headache, a diamond on her finger, and a six-foot-three problem named Luca Leone. Billionaire. Ex-playboy. The man she’s argued with since they met.
He proposes a deal: stay married long enough to convince the world he has moved on from his ex, and he will save her family’s home from financial ruin.
No feelings. No complications. Just legal paperwork and luxury photo-ops.
Except Luca’s touch short-circuits her common sense. His protectiveness feels too intimate. His kisses feel like promises. She knows better than to fall for her enemy.
Yet every night in his penthouse tells a different story.
What happens when a revenge marriage turns into a love she can’t walk away from?
Tropes: billionaire, enemies to lovers, marriage of convenience, fake relationship, penthouse proximity, grumpy/sunshine, sinful tension
