The truth was that Chen Kun didn't want to lock the door, but things were already out of his control.
Inside Room 511.
Chen Kun had originally been watching the door. After Zhang Wei and Guo Jintao had left one after another, he stood at the doorway, sticking his head out and observing the movements outside, focusing all his attention on the corridor.
Before Guo Jintao left, he had casually slapped the sleeping Han Zhao twice, telling him to get up quickly, but Chen Kun hadn't paid attention to it.
As a result, Guo Jintao had been gone for quite some time, and Han Zhao hadn't stirred, let alone gotten out of bed, and Chen Kun hadn't noticed at all.
His mind was still outside, on the departing figure of the man in the black tank top, Chen Rui'an.
It was already quite abnormal not to have any reaction to being slapped awake from such close range.
