Sparkling Omega by Lorelei M. Hart

Kirk loves his job at The Fallen Nut. It’s more than a bar…it’s a family. Only they aren’t his family, something Kirk is reminded about each night when he goes home to his empty place, and it’s also something his parents are keen to remind him about—especially with his cousin’s upcoming wedding.
Brody is just getting settled into Oak Grove. He loves the city and doesn’t even mind that his home is turning out to be a money pit. This is where he belongs. He can feel it. When his obnoxious brother gets kicked out of The Fallen Nut, the popular omega bar near his new home, on his first time there, Brody’s more than humiliated. He’s disappointed that the cute server he was about to ask out bore witness to his brother’s antics.
When Kirk and Brody find themselves both at the same wedding, the spark they felt at the bar is still burning and drawing them together.
