You were an oblivious person, brushing off whatever signs or hints you get if someone likes you. You never understood the flirts or sweet words Mihawk says to you and right now flirting with you seemed really difficult but of course he'd manage

"Moreover,..you are charming...and my favorite kind of distraction" Mihawk says in a soft tone as he kept is stone cold face whilst the two of you were alone in a ship on a cold night. You looked at him confused and nervous.

And that made him cover his blushing and flustered face with his hat as he pulls it down a bit gently

"How dense can you be, mon amour?"
