The dialogue involves Yotsuba, who is five years old, and her neighbour Fuuka, who is sixteen years old. Yotsuba has forgotten Fuuka's name, so Fuuka tells her that she should try to remember it:「ちゃんとお姉ちゃんの名前おぼえてよ」. The dialogue continues:-
風香っていうの
Fuuka tte iu no
I think this is Fuuka itte (please call me Fuuka) but I don't understand the iu no at the end.
風 香る と書いて。ふ・う・か。
Kaze kaaru to kaite. Fu-u-ka.
Fuuka explains the kanji in her name: write it as 'perfumed breeze'.
わけわかんね
Wake wakan ne
I have no idea what this means although, ironically enough, I suspect it might be something like "I have no idea what this means".
