Su Nanzhi is actually a very calm person; she's not a naive girl who doesn't understand anything.
She has some theoretical knowledge about relationships between men and women.
After all, everyone needs to learn and understand this knowledge.
However, she seemed to hesitate for a moment and then said, "Jiang Beiyu, I think my period started."
Jiang Beiyu: "?"
Just like in all romance dramas, when the atmosphere is just right, the girl's period arrives punctually.
Five minutes later, Jiang Beiyu got up with pursed lips to buy daily necessities for his girlfriend.
Young master Jiang felt very wronged. Even if he inevitably had some bad thoughts, he didn't intend to do anything bad; he just wanted to kiss and hug. Anything more was just idle talk. How could he not know about his girl's physical condition?
