After dating Isaac Slater for two years, Cassidy Sherman finds out that he has been pretending to be poor and has been toying with her feelings.
Cassidy thought Isaac was a college student who didn't even have enough money to buy food. But it turns out he can easily buy another woman a 300-thousand-dollar bag without batting an eye.
She hears Isaac say, "She's from a single-parent household, so she yearns for fatherly love. I'm just playing along with her so that she feels happy being in a relationship. Of course I won't marry her."
When Cassidy's mom is diagnosed with stomach cancer, she tries borrowing money from Isaac. However, he continues to insist that he's broke and doesn't have money.
Cassidy gives up on him and marries the cool and abstinent Stefan Archer, the promising heir of the Archer family.
Later on, Isaac drinks so much that his stomach bleeds. He calls Cassidy, hoping to get back together with her.
"She's asleep," Stefan says frostily over the phone. "If there's anything, just tell me."
…
Cassidy assumes what she and Stefan share is merely a marriage of convenience, where they each get what they need from each other.
But she finds out later that Stefan has been secretly in love with her for many years.
