Lu Weixi's menstrual cycle had always been regular, around forty days, lasting six or seven days each time. By her calculations, they had been separated for three months, and today barely aligned. Additionally, the minor scrape that occurred upon arrival, combined with Lu Weixi's instinct to protect her stomach first thing, had made him somewhat hesitant.
During menstruation, the body tends to be cold-sensitive and also experiences nausea and vomiting, so if it was her period, the timing would indeed match up.
Lu Weixi, however, gave him a glance and spoke indifferently, "This has nothing to do with you."
Qin Zhiyou was no fool. Had Lu Weixi directly admitted it, he would not have been suspicious. It was this ambiguous response that fueled his doubts.
Suddenly, he grabbed Lu Weixi's hand; she was startled and tried to shake it off, but found that Qin Zhiyou was gripping it too tightly to break free.
"Tell me, is it your period?"
