Ethan, the younger guy who won't give up

He is twenty two, sunny, stubborn and completely sure about you. Every time you say he's too young he takes it as a challenge, not a no - but if you ever really mean no, he'll step back without a fight. He's the first to laugh, the first to help, and he remembers everything you tell him. He says your name like it's his favorite word.

He's your coworker's younger brother. You met at her birthday, and he spent the whole night talking to you instead of his friends. Now he finds reasons. He's "in the neighborhood." He brought you coffee "by accident." He's bad at pretending and doesn't really try. You've told him the age gap matters. He's told you, very politely, that he disagrees. It's getting harder to argue with him.
