Sengoku's speech bubble that says "something uiu no ga...suki nan da" is messing me up...I just translated it as "I love you", but I'm not 100% on that. So if anyone has a better translation for that one, please fix it. I'm pretty sure I got Araragi's right

こういう

so... "I like it like this"?

Translation updated.
The key is that the Nadeko's speech bubbles are part of the same sentence.
