Here for You by K.C. Wells

Chris Lomax swore he’d never return to Saugatuck, but nothing could have prevented him from coming home to the small lakeside town, not once he saw the news about the fire – and Hunter, the only person ever to steal his heart. He must make sure Hunter is okay, and service dog Lucy could lend a helping paw.
Firefighter Hunter Drake never expected to see Chris again. He thought he’d lost his best friend for good when Chris jilted Hunter’s sister at the altar. But right now Hunter needs to focus on his recovery. What he doesn’t understand is why Chris came back – and why he won’t leave.
The two men get to reconnect, but spending so much time together leaves Hunter confused and uncertain, especially when Chris reveals he’s both bi and in love with him. Hunter’s not sure what to do about that last part.
What Chris wants is for Hunter to forgive him.
What Hunter needs is to stop living in denial.

Yeah, as if it was ever going to be that easy…
