Short-term Daddy by Charity Parkerson

Jarek is burned out on life. One summer night with a sweet soul changes everything.

While Luca is used to being considered odd, he’s embraced the title. He’s found happiness in the simpler things. It’s not like he has a choice. He’s dirt-poor living in an expensive town. Barely scraping by isn’t even enough to describe how dire his straits are. Then a chance meeting at the park turns his entire life on its head. He’s never been more terrified. This one will hurt when it’s over, and Luca already knows how it’ll end.
As a highly sought-after attorney, Jarek hasn’t taken a breath in years until one night he simply decides to stop. When he spots an adorable man playing with blocks in the middle of the park with zero shame, Jarek can’t stay away. He keeps searching for ways to convince Luca to see him. Jarek can’t even say exactly what he hopes to achieve, but he only has one summer to figure it out. After that, Luca will be gone forever. That’s not an outcome Jarek is sure he can handle.
