The call Qin Qingnan made was naturally to have someone investigate the roommate of Ou Lan that Li Dan had mentioned.
Investigations take time, so while waiting for the results, Qin Qingnan distractedly and anxiously fiddled with his phone, while Xie Shichen sat beside him, showing no intention of leaving.
He was afraid that once Qin Qingnan learned the truth, without his persuasion, this fool might do something irrational.
As time ticked by, Qin Qingnan grew increasingly anxious. It was as if there was an invisible force pulling at him, leading his thoughts naturally towards Lin Ziran.
"Shichen, do you think, the roommate of Xiao Lanlan that Li Dan mentioned, could it be Xiao Ran?"
Although he had suspected it might be Lin Ziran for a while, Xie Shichen refused to say so. He just smiled calmly, "As policemen, we never express opinions without evidence."
Qin Qingnan exclaimed "Damn it," and lowered his head to play with his phone again.
