Lost in Fifteen

Lily Bennett made a bet with Jason Whitmore's first love: if she couldn't seduce him within 15 attempts, she would leave; if she succeeded, the other woman would step aside. On the 15th attempt, she slipped him something — but he humiliated her. Only then did she realize that he felt no desire for her, and had married her just to suppress his feelings for his first love. Lily planned her escape, but Jason kept hurting her. It was only after she really left that he woke up and started chasing her.
