Hello, The chinese text is taken from www.qiqi.com, just to fill in the blanks.
" You meddler ... (unable to figure this bit out)!" he growled arrogantly. " (unable to figure this bit out)?"
那公子怒道:“关你屁事?你自己看上了这姑娘是不是?”
My version -> "how does this concern you? Have you taken a fancy to this girl?
(Note: 关你屁事 guan1 ni3 pi4 shi4 is a very vulgar/rude way to ask. something like "how is this fart mattter your concern")
" Enough! So, you will return it or not?
郭靖摇头道:“不是!你到底还不还?
My version ->"No! will you return it or not?"
