"Look, I appreciate the thought, but..."
To be honest, right now, Miu feels pretty exhausted. With the lack of sleep she's had recently, the hard work she's been putting in at her job, and what's seemed to be a string of bad luck incidents one after the other, it feels like life has just been throwing things at her lately without any room for a break.
Miu's not stupid, obviously. She knows how popular Hawks is - he's probably the most popular hero in Japan right now, even without that official number #1 rating. She's not a huge hero fanatic herself, so she's never been hugely interested in him, but even she feels a little nervous to be talking with the man; knowing what a rare chance it is and how many people would die to be in her spot.
But... even with all that in mind, she wishes this choice hadn't been sprung on her so suddenly. It's not like she's suspicious or anything, but the offer he's made is one she needs to think about. She can't help but worry that she'll make the wrong decision...
"We're not looking for a collaboration right now. I'm not saying I'm not grateful... but what made you seek us out, anyway? It's not like we're huge names or anything."
