Shang Junxiao was both angry and embarrassed. He asked the property management for help and even offered to call the police.
The property management then communicated with the neighbor, as the surveillance footage indeed did not capture the segment Shang Junxiao alleged to be stealing underwear.
It also didn't capture any underwear falling from upstairs.
Even if Shang Junxiao was a pervert, he couldn't possibly steal the underwear back to his home without anyone knowing.
The property management felt that the underwear was probably the same kind, and the neighbor had made a mistake.
However, the neighbor insisted it was their underwear, with the brand, color, and size all matching.
Shang Junxiao, greatly upset, then requested to call the police.
In the end, the neighbor couple, probably feeling not quite justified, said they would let it go this time, but if it happened again, they would be the ones to call the police.
