"How can you be so dumb!" Luo Mengmeng clutched her heart, staring at her with a look of exasperation, "Are you even a girl, how can you not know about the menstrual period..."

If there had been a mirror present, Luo Mengmeng would have noticed that her expression was identical to the one Gu Zhihan had a few hours earlier.

Gu Zhihan watched the little girl in the living room explaining menstrual periods to another girl about the same age, and couldn't help but twitch the corner of his mouth.
This guy really knew how to learn and sell immediately...
