お空の読み方
「おそら」と「おぞら」は、どちらが「お空」の読み方？どちらもがいいですか？ならば、違いはありますか？そして、「空」だけはいいんじゃないですか？「金」だけは、たしかちょっと失礼です。
文法の間違いと不自然なところを直してください。

How is お空 read, おそら or おぞら? Are both options ok? If so, is there a difference between them? And　just 空 (without the お) is ok, isn't it? If I recall correctly, just 金 is a bit rude (mafia-like).
Please correct both grammar mistakes and also anything unnatural.
