Mr. Su felt guilty and blamed himself for his negligence.
"I… Some students came to me yesterday and asked me for a list. I was in a hurry, so I didn't go upstairs myself. I asked the other girl to check the rooms for me…"
"Oh, so are you saying that girl did not notice Sun Huihui as well?"
Ning Li looked at Sun Huihui.
"Mr. Su usually checks the place around the same time just before sunset. When you were locked up, didn't you try to scream for help? Surely someone would have noticed you, right?"
Sun Huihui was speechless.
She had screamed as loud as possible, but…
She had involved both girls because she had wanted them to work with her just so she could trap Ning Li.
Who would have thought that she would be the one who would end up trapped inside the janitor's room instead?
After hearing Ning Li's theory, Sun Quan and Mr. Su noticed something fishy.
