Ella stayed static for a while the moment she woke up. She had to let the memories sink in, why she was in not so familiar surroundings. Then she remembered that she was already inside the sorority house and got her own space in that house.
Aside from that, she knew that she was with Adam last night. They had great sex for her first night in the sorority house. She felt so wild and so spontaneous.
If she was her old self looking at her at that moment, she couldn't believe that she would do something like that. Ella had always planned her life, and she was content with her mundane and less risky life.
She even remembered herself being the last one who would never imagine being part of the sorority compared to all of her friends. She was the last person who would likely make herself in that house. Ella didn't know if a stroke of good luck made her inside that house while her friends did not. Since she only made it because of Adam.
