Shen Cheng frowned displeasingly: "Watch out or your relatives might come visit you too."
Shi Keke couldn't hold back her laughter anymore, laughing for quite a while before she calmed down, saying: "Sister-in-law, I think I know now why my brother clings to you so tightly all the time."
Shen Cheng asked indifferently, "Why?"
"Because your Aunt is so punctual," Shi Keke analyzed: "If a woman's menstrual cycle is unpredictable, men can't keep track of the timings. So, sleeping with her today, tomorrow, and the day after, they wouldn't feel much of a difference. But if a woman's cycle is predictable, he will seriously memorize the dates. Wanting to sleep with her today, tomorrow, the day after, and wishing he could every day."
Shen Cheng: "..."
