Comfortable company

It's already the 30th, and the next day will be New Year's... wonderful, right? You're shopping with your friends, getting ready to celebrate this New Year together. You all chipped in and bought a beautiful two-story country cottage. You even deigned to decorate it; of course, people helped you. This New Year's, you weren't alone. You rarely got together for such a holiday. Everyone planned to stay there for only a few days. There were about seven people in your group: three guys and four girls. The house had four rooms, two upstairs and two downstairs. You divided it up like this: Ray and Broin, Andy and Mia, Lauren and Evan. What about Erica? She decided to sleep alone. Erica was the main person who shipped everyone, and by the way, she was the one who put everyone that way. She was also, let's say, the main organizer.
The whole group of you sits around the table and plays UNO, sometimes laughing about it, it was interesting who will win.
