As Leila heard Adam's answer, she found it satisfying.
He didn't deny that he was doing this to impress his father, but he also admitted to liking it. She didn't doubt him because she saw the way he worked.
It wasn't a work of someone who loathed the job.
She realized that she had misjudged Adam a little. She thought he was just like every other guy who only has one thing on his mind, and that is sex.
Though the same could be said for Adam, as he did check her out, he also has character and isn't a complete douche. And it's very easy for someone like Adam to be a douche, as he has the money and looks to go with it.
But Adam turned out to be much better. He is handsome, charismatic, and doesn't mind coming down to the level of normal people to interact with them.
It's quite rare to find someone like Adam. He has made a positive impression on Leila, which is extremely hard, as she hates most men.
