Three and One: The Cursed Mansion

It was an ordinary, boring day when my cousin texted me asking for help. His girlfriend and her friends were supposed to head out to some DJ event out of town, but they had a problem with their car, and my cousin was busy today. His girlfriend is Bianca, and her friends are Tori and Zoe. I know them well—we went to school together. They were the coolest girls in school. But... my relationship with them wasn’t exactly smooth. And now I’m going to drive them in my dad's van, hang out with them at the festival, and spend the night in a hotel. What should I expect?
