A little ambiguous

Sheng shuangxue went back to her office to sort out the evidence after work. Zhao Si Yan had some family matters to attend to, so he left first.

After she was done, she passed by the office of the criminal Police unit. The lights were still on.

She looked around and saw no one. She knocked on the door."Who's still here?"

There was no response.

She mumbled,"did I forget to turn off the lights?" He didn't even lock the door, " and turned off the light.

"Didn't I say I'll turn it off?!" A roar suddenly came from the darkness.

Sheng shuangxue was shocked. She opened the door hurriedly and saw Gu Yunhao coming out of the small meeting room next door.

She asked,"why haven't you left yet?" I was so scared!"

"I'm leaving." Gu Yunhao said tiredly. He came over to turn off the lights and close the door. When he realized that she was still standing, he turned to look at her.

Sheng shuangxue felt that she was being a busybody. She snorted and strode away.
