Yuan Shu hurriedly changed out of her gown and put on a large white T-shirt. Then, she changed into a pair of comfortable cotton pants. The rubber band on her hair had just been taken off, and her curly hair was draped over her shoulders, but she didn't have time to tidy her hair and hurriedly left the room to go to Shi Yi's room.
She knocked on the door first, but there was no response. Yuan Shu was a little worried, so she knocked harder, but there was still no response.
Yuan Shu said, "Shi Yi, are you in the room? Can I go in?"
There was no response.
After Yuan Shu waited for about ten seconds, she couldn't wait any longer. Just as she was about to break in, a muffled voice came from inside the room. "The door isn't locked. Come in."
