Removing start of a string results to following characters replacing it - C#

I'm currently writing a project in C# (I'm new to C#, so excuse me if this is a stupid question).
When I cut the start of a string with text = var.Substring(4, var.Length - 4);, it returns a result that i don't want.

Here is a snippet of my code:

string lines = "say \"Hello, World!\"\nsay \"Hello, World!\"";  lines = Regex.Split(lines, "\n");  foreach (string line in lines)  {      Console.WriteLine($"'{line.Substring(7, line.Length - 7)}'");  }  

I expect the output to be '"World!"' (two times), but this is the actual output.

'"World!" // Why is the last quote missing?  '"World!"'
