Is there any way to make "nopagebreak" work before "paracol"

I need to build the following structure:

Title

——————— [paracol starts]

contents inside paracol

——————— [paracol ends]

But when the title is at the end of a page, I want to apply nopagebreak to the title in order not to leave the title alone.

However, nopagebreak does not work before paracol.
Is there an alternative to make it work?

The following is the actual code and its output.

documentclass{article}
RequirePackage{paracol}

begin{document}
vspace*{18cm}
Title above paracolnopagebreak[4]
begin{paracol}{2}
rule{textheight}{1pt}

contents in paracol
end{paracol}

end{document}

documentclass{article}
usepackage{paracol}
usepackage{needspace}

begin{document}
vspace*{18cm}
needspace{3baselineskip}
Title above paracol
begin{paracol}{2}
noindentrule{columnwidth}{htstrutbox}par

contents in paracolpar
end{paracol}

end{document}
