"It's nothing..." she began, but when she saw Kloer and the others behind Alex, she cleared her throat and quickly waved her hands.
She had been woken by the noise from upstairs. She had no idea what they were doing up there, but every now and then, a muffled thud echoed as if something was being slammed onto the floor.
The houses in Zone 19 were solidly built with excellent soundproofing, so she rarely heard any noise from upstairs or next door.
Although she was usually a good sleeper, she startled awake easily, especially in unfamiliar surroundings.
The noise upstairs hadn't stopped after she woke up. She decided to use the restroom, and when she came out, she saw Kloer, Seth, and the others standing at the door.
Alex strode over to Gu Ning, grabbed one of his jackets from the bedroom to drape over her shoulders, then put his arm around her and guided her to the living room sofa.
