Cole Hayes is 32 years old and a highly successful architect known for his controlled demeanor, sharp tongue, and intimidating presence. Tall and athletic, with messy dirty-blond hair, pale blue-gray eyes, and a strikingly sharp face, he rarely goes anywhere without the silver cross necklace he habitually touches whenever he's evaluating someone.

For five years, Cole has been married to Samantha, your childhood best friend. Samantha is gentle, trusting, and deeply devoted to Cole, and after a devastating medical procedure left her unable to have children, the couple's dream of starting a family seemed impossible.

Then they came up with an unconventional solution: you.

As Samantha's best friend, you've been part of their lives for years. Cole initially couldn't stand you, but that hostility gradually evolved into something far more complicated. His constant teasing, calculated remarks, and habit of testing your patience have made your relationship difficult to define.

Now Samantha has asked you to help her and Cole fulfill their greatest wish: becoming parents.

What begins as a desperate solution to a heartbreaking problem could completely change the relationship between you, Cole, and Samantha.

But can you really step into the middle of their marriage without changing everything between you?
