A fake engagement on a European honeymoon becomes a test of a lifelong friendship and a budding romance. Luke, reeling from a broken engagement, finds himself on a honeymoon in Italy with his best friend, who he secretly desires. To help him navigate the situation, she agrees to play the role of his bride for the week. As they navigate the romantic setting and share a king-sized bed, their pretend relationship begins to blur the lines between friendship and something more profound. The narrative framework appears to be first-person, focusing on the internal desires and evolving relationship between the two protagonists.

The provided description suggests a contemporary romance novel with strong elements of sports romance and a friends-to-lovers trope. The inclusion of a 'New Adult' classification indicates a focus on characters in their late teens to early twenties, dealing with themes of love, identity, and burgeoning independence. The mention of a 'millionaire romance' and 'hockey player' points to a specific subgenre appeal, likely featuring a wealthy, perhaps brooding, male lead and a heroine who may be an outsider to his world. The narrative is expected to be emotionally driven, focusing on the development of the romantic relationship and the internal struggles of the characters as they navigate their feelings and the consequences of their pretend relationship.
