Thanks for all the translations! Aww, Kanata's squirming is perfect. Haruki is surprisingly pretty chill as far as TS moe goes (almost identical to a born imouto) so it's fun having someone squirm about gender stuff.
And yes, boys, just give it up. Haruki's only for her aniki.
I started to think Haruki's friends might have been reading some 'certain' doujins (from Yasumi Mirakichi) a lot and get some weird idea about the situation...
