Mondscheintarif (2001)

You must never call a man after your first night together! He has to call you!

To call or not to call? For young Cora it's not a question. In fact, after the first date you may never call the guy, even if it was the best sex of your life! It's him who must beg for a meeting - and not later than 72 hours after. Otherwise - delete it from memory.
