英语正确翻译：从此除你以外不会在有

不知道楼主是不是要表达从此“在我心理除你以外不会在有别人”。

there won't be anyone but you （in my heart)from now on.

anyone but you 除了你之外不会有别人。

There is nobody but you forever

In addition to you from outside would not have

There won't be any one but you henceforth

There won't be any other one but you from now on~
或者是:There won't be any else but you from now on~
