Hi, It's without a doubt,
Walking in the Sand by Axell
Summary:
He's what you'd call a catch: young, good-looking, cultured and rich. Women tripped over themselves to get his attention, but he long ago gave up on seeing himself as a fully functional male with wants and needs, focusing only on his guardian role. He's doesn't have time to socialize with the annoying bints anyway, always too busy taking care of Dru.
That changed one day when a blond, green-eyed landmine with a ridiculous name and her cat, with a name even more ridiculous, barreled — literally — into his life, forcing him to acknowledge that he wasn't dead and buried along with his family. From the first moment, she captivated him, making feel things he had no business feeling, especially when he's not a free man, at least, not from his perspective.
