[Bless. Smoker will start calling him a secretary bird too, even if Marco is the more curbstomping type.]

He's definitely fond of you, or he'd avoid you, marine or not. He never wasted time hanging around Sakazuki. Or Borsalino. And he has a soft spot for marines who do things that would get them otherwise court-martialed, but are the right things to do. And where he spends his time is the only freedom he could claim for himself at his rank, so it means a lot to him. If he chooses to spend it with you, he likes you.

Yeah, see? Sounds fun. Enjoy it.
