This was a really cute book! It was a really good low-angst, quick read. I've been enjoying the age-gap/dad's best friend books a little more lately, and this was a great one! I really enjoyed that the younger partner wasn't just out of his twenties, too. Lukas had an established job and his own house and pets, and he was stable in his life, which isn't always the case with a dad's-best-friend book. I liked John a lot, and I think he was perfect for Lukas. He was looking for a partner who he could take care of, but also one who wanted to take care of him, too, and Lukas was everything he needed. His struggles with coming clean to his best friend made Lukas feel really insecure, and threatened to break the relationship a few different times, but each time, John was quick to assure Lukas that he was in it for the long haul. It felt really realistic the way that both of them handled their insecurities, and it was nice to see that they each realized when they messed up and always apologized in earnest. Also, the filthy mouth on John and the things it did to Lukas were a big highlight of this book. If you enjoy a little light kink exploration sprinkled in with a lot of dirty talking, this book will be a real treat for you. I'm definitely going to read more of the books in this series!
