The one knocking on the door was Zou Lan.
She had seen Su Tu and Tong Gui entering the lounge one after the other, which seemed suspicious, especially since the door was then locked from the inside; it was hard not to let her imagination run wild.
She specifically told He Xiaoxiao about it, who, upon hearing the news, immediately instructed her to knock on the lounge door to see what Tong Gui was up to.
A minute later, the door opened, with Tong Gui stepping out first.
Zou Lan's gaze scanned Tong Gui's face like a radar, eventually locking unblinkingly onto Tong Gui's lips.
Although she had a boyfriend, she couldn't help being suspicious, as there was something unusual about Tong Gui's lips.
Before she could confront Tong Gui, Tong Gui approached her and whispered, "You were the one behind my foot injury last time, weren't you?"
Zou Lan was stunned, "What nonsense are you talking about?"
Tong Gui looked straight at Zou Lan and found that Zou Lan didn't seem to be lying.
