It had to be this way.
The voice in the recording must be extremely, extremely similar to Gu Yi'an's, so much so that it could easily be mistaken for hers.
Only then would Lu Moran be so frightened.
If the voice was merely imitating Gu Yi'an, even though Lu Moran might think it sounded a lot like her, he could still tell from subtle details that the voice wasn't hers. If that were the case, he would have had no reason to keep the recording, and would have immediately handed the phone over to the police to let them find the person on the recording.
Because if that were the case, it meant someone was trying to frame Gu Yi'an.
However, because the voice on the recording was so indistinguishable that even Lu Moran couldn't determine if it was really Gu Yi'an or someone imitating her, he didn't dare to turn in the recording!
Once he turned it in, Gu Yi'an would certainly be taken away by the police as the prime suspect!
