Shangguan Xiu really believed it, because when he was with An Xiaomian before, she often suffered unbearable menstrual pain.
Although he had treated An Xiaomian for it long ago, the effect was not significant, and she still experienced frequent pain.
The only thing he found strange was that he remembered her period didn't seem to be these days, but because he was a doctor, especially one who had researched a lot to treat An Xiaomian's menstrual pain, Shangguan Xiu also knew that many girls' periods are not very regular, and the timing is not accurate.
So the next second, Shangguan Xiu turned around and no longer looked at An Xiaomian. With his back to her, he said coldly, "I'm going to eat something first. Miss An, you'd better follow! If you haven't come over in 5 minutes, then don't bother coming at all!"
After speaking, he walked away indifferently.
