"Who's there?"
Shen Qianqian muttered, puzzled.
She mostly lived alone and had few visitors aside from Xue Qiqi and Xia Qingqing, with male friends being even rarer – Lin Chuan was probably the first.
And most likely, the only one.
Father Shen was drunk, and Mother Shen should have been at home tending to him, so she was somewhat perplexed as to who would be knocking on her door at this hour.
— The reasoning of a professional detective.
Under the dim yellow light, Shen Qianqian stood up and walked toward the door, peering through the peephole, only to find an empty, pitch-dark space outside – she saw nothing.
No one?
Shen Qianqian was somewhat startled.
"Who is knocking?" Lin Chuan came out too, and several seconds had passed without Shen Qianqian opening the door, prompting his curiosity.
Shen Qianqian shook her head: "No one."
"No one?" Lin Chuan frowned.
"It might be some kids playing a prank," Shen Qianqian guessed.
"Let me check."
