Qian had previously obtained two pinhole cameras at Arcana, intending to install them in the bathroom to observe Xiaoqiang's state while relieving himself—don't ask her why she's so bored and has such a quirky taste, she's just curious about whether Xiaoqiang, who poses as aloof outside, holds a shampoo bottle to study the instructions, or stares at the ceiling contemplating life while squatting.
Because this guy doesn't smoke like other men when relieving himself, nor does he bring a book, nor does he play PSP, so Qian got playful and thought of this trick. There must be plenty of this equipment in a laid-off agent's stash. She had no psychological burden in pranking her own husband a bit.
However, this plan was discovered as soon as it was implemented.
Qian thought she had placed it very secretly, how Yu Minglang discovered it is a mystery.
For this matter, she was severely dealt with by him. That process is better left unsaid...all tears...
