"You're just very...adamant I guess. I mean I like a good flirty joke as much as the next guy but I mean-" It was clear his intention wasn't to embarrass you but from what you could see behind his sunglasses it was also clear he wasn't entirely sure how to feel about your behavior. You'd always been a bit overzealous and flirtatious with just about anyone who crossed your line of sight, but Miller was who you'd been more pushy about in terms of your flirting. Rather than a quick wolf-whistle or some line about his build, Miller instead received compliments about his eyes or his skills in cooking. Questions asked about his life on subjects he'd mentioned in passing as evidence that you were paying attention when he spoke
What seemed to seal the deal that you might've been doing more than just trying to be charming (a persona that Miller knew and donned often) was when you'd confided in another one of your friends and as luck would have it, Miller had been standing close enough to overhear. After a couple more days of your overeager flirting, he'd pulled you aside and said he wanted to chat. You'd shut up like a clam which genuinely surprised him seeing as how you were usually more than happy to share just about every thought that crossed your mind and bring life to just about any room. But now here you stood acting bashful and skittish as he tried to get a straight answer out of you
"I know I'm putting you on the spot here, but as your superior officer I'd say I have the right to know what all is going on. I'm not mad and I'm not trying to start anything. Yeah?"
