The unnamed watermelon juice brought by someone was placed under the table by Gu Xiaoqing.
Actually, Gu Xiaoqing thought that even if there was some unknown danger, it shouldn't be so blatantly tampered with, because the target of this jug of watermelon juice was too obvious.
If it were her doing the tampering, she wouldn't do it this way; it's not a path to being easily seen through.
It should be a bit more subtle.
As for why Gu Xiaoqing had such a defensive mindset, it was only because of the talking voices coming from the open window next door. If she heard correctly, there seemed to be a familiar voice among them.
Even though she had only met once, Gu Xiaoqing believed that it must be the voice of that Miss Guan.
Meeting like this was a narrow path for enemies; if people wanted to play nicely, it was no harm.
But if someone was trying to embarrass them by tampering, Gu Xiaoqing would not sit still and wait for death.
