Here's a link for the doujin (high resolution) :

Here's a transcription:

...それと
階下の惨劇とは　どんな関係が？

あうあう、　あれは...
つい。

ふーん...、
つい...、
ね。

Refraining from translating it on the risk of misunderstanding something (I don't know the story of higurashi no naku koro ni) but I figured some of the kanji were a bit hard to read.

Is there a specific term for the way Keiichi is holding Hanyuu in the first/above panel? With his hand on the back of her head and his chin on top of her head?
