Iris couldn't sleep at all.
She woke up multiple times during the night, feeling strange in someone else's house.
The unsettling thought that someone might be watching her sleep lingered in her mind. However, she knew it was just her imagination, as she had checked the locked door several times. Still, the presence of the black door unsettled her, and she found herself falling asleep while holding a knife, just in case.
As dawn approached, Iris gave up on trying to sleep and decided to change her clothes. She spent her time reading through the documents that Justin had given her. The files were well-organized, containing all the subjects she needed to study. Grateful for the assistance, she quickly went through the material and mastered it.
In the files, she also found her class schedule for the current year and tried her best to memorize the information. Once she finished reviewing all the files, she heard a soft knock on the door.
