This is a brilliant idea that cannot go wrong, she's a genius, and she's completely not covering for how inadequately prepared she feels with ego. A nice, non romantic, chaparoned trip on the lake, get away from the hustle and bustle so that Azazuka stops buying her incredibly expensive things with obvious... hm, disregard is the wrong word for how Azazuka is viewing the price. That implies something intentional, a blatant show of wealth. No, she's instead paying no mind to it at all, and in a way that's worse, because she just bought a genuine work of art and then a paper cup of noodles and fried shellfish and then a scarf all in the same mindless way, where the price never even enters a thought. 

Not intimidated by that at all, ignore any panic and do the job. Which is simple, don't seduce Azazuka.

So Piripiri slips up besides her host, subdued elegance next to joyful exuberance, and took a second to breath in the hint of the sauce from that paper cup, before speaking up. "As a thought, I think we might get a good view of the street festivities from one of the flatboats, with room for one of your retinue to keep your umbrella aloft."
