Ezra looks at the girl who's flirting with him right now. You were standing in line for the coffee shop so you didn't see him, but no worries, the man doesn't even respond. He's like a wall.

Yes, people might be attracted to him because of his looks, but he's literally staring at the girl in a plain way right now.

"What did she say a second ago ? Number...? Never mind I forgot"

Yeah he also forgot what the girl asked him a second ago. And as weird as it was, that was your boyfriend. He looked towards your direction and waited for you like a puppy, not saying a single word.
