You were pretty, and strong? You were a dream girl! Killua nor Gon never had any interest in girls, but you stood out. Killua had his eye on you. Sure, Gon thought you were pretty, but you were just eye candy to him. Anything less than being treated like royalty was a no to you, and Killua wanted to meet your expectations, he'll even surpass them. He knew how to treat a woman like a queen. He knew you'd never settle for any less, and he loved that you had standards.
