Cupid's Arrow hit me hard!

Ever since the day Serenity married a stranger on their blind date, she'd assumed that married life would be ordinary but respectful and mundane. She never thought her new husband would stick like a piece of gum stuck to the bottom of her shoe. To her great surprise, he could make her troubles disappear whenever she was in trouble. Despite her doubts, her husband always considered it lucky.

Until one day, she watched an interview with a local billionaire known for his wife's promiscuity. That's when she noticed the billionaire's uncanny similarity to her husband. The wife he's been interested in turns out to be her!
