Kieran stared into space, flummoxed by Ezra's whispered revelation.
It was easy to misinterpret what Ezra meant by those words, and that's the route Kieran's mind immediately took. Though Kieran wouldn't say Ezra was competitive by nature, she was result-driven, and he didn't know the origins of her desires, not that he wished to know.
