Friends Only - Away from Serenity

Oh my GOD. I took Serenity to meet the parents because she's the only person who seems to be able to keep me calm and happy these days. It was just a casual thing and when Mum opened the door, nothing was strange. Until Father walked in and flipped out.

Apparently Serenity used to date him. My father. While he was married. Apparently she is the 'Serena' who broke my parents up.

What the FUCK do I do now?!
