The caller was Jiang Man, also a member of the lab and Zhao Min's roommate.
"Yesterday, you called her, and she said she was going back to the company to do an experiment. But this morning, I woke up and found she hadn't returned. I tried calling her, but her phone was off. She never turns off her phone. I... I'm worried something happened to her," Jiang Man said anxiously.
Song Fan remembered Jiang Man as a quiet girl who usually kept to herself in the lab. In the days Song Fan had been there, Jiang Man had spoken less than ten sentences to her. Now, her sudden outburst of words showed her genuine concern.
Song Fan checked the time; it was almost six o'clock. Zhao Min should have returned home hours ago if she had finished her experiment by eleven last night.
"Jiang Man, don't worry. I'll head to the company right now. Maybe she's still in the lab," Song Fan reassured her, although she knew the chances were slim.
