[That's kind of the funny thing. Rei isn't deliberately flirting. She's just talking and telling the truth. She'd like to get to know Naoto. She means it platonically, but you can go on a date with someone and still think of it as platonic. It's a means to pass the time, after all.

And that reaction, well, that's cute. That's extremely cute. So cute it almost burns, and she giggles. She can't help it.]

It's a good look for you. And I'm glad you don't mind my company.

[By now she's reached the restaurant, and pushes open the door for the very embarrassed detective.]

I'm just telling you that I think you're smart, and I think you're interesting. Don't worry. I don't bite or anything.
