Literally none of 13 Deuterium's protagonists ever mention periods.
Even though half of his protagonists go through gratuitous amounts of misery and poverty porn apparently having your period while not having access to sufficient toiletries is crossing the lines and truly destroys the fantasy of becoming a (poor, persecuted) beautiful girl.
Even Ji-eun, who is a literal hobo camping out in an abandoned village for half the story and gets pregnant three times never mentions periods.
