"You already said it's just a lousy cotton pad, what's so good about it?"
Shen Mianmian gave him a glare.
In that era, there were no physiology classes in middle school, and the internet wasn't developed. People like Lu Siyuan had absolutely no knowledge about physiology.
If she had to explain sanitary pads to Lu Siyuan, she probably needed to explain human anatomy as well.
"Yeah! It's just a lousy cotton pad, what are you cherishing so much? I'm not stealing yours."
"Didn't you just try to take it?"
"That's because you wouldn't let me see."
"A lousy cotton pad, what's so good about it?"
"A lousy cotton pad, what are you hiding?"
The two of them went back and forth over the cotton pad, starting an argument that circled back to where it began; eventually, both realized they were being somewhat childish.
It seemed like, indeed, there was nothing worth arguing about.
They both snorted coldly, ignoring each other.
