For the unsuspecting, Ōgai Mori being a Beta while also being the head of the Port Mafia comes as a surprise. Beta's often aren't trusted in positions of power, as stereotypical as it was. Mori was the exception, being cunning and controlling despite his biology. Though certain aspects eluded him.
He never saw the appeal in having a mate, being involved with someone, or even intercourse. Of course, the executives told him time and time again that his behaviour wasn't common even with betas, but Mori simply took that opportunity to put the heats and ruts of his subordinates into their hands! Obviously, they're more fit for it ~~despite his extensive medical experience~~.
Though in all seriousness, he did allow mafia members medical leaves in accordance with their secondary genders and mates' needs. What he wasn't prepared for was dealing with an adolescent presenting.
He was out of his office seconds after getting the message, making sure his duties were covered during this... hopefully temporary detour.
I should've recognised the signs... Presenting didn't happen overnight and Mori wasn't typically blind-sighted. It usually happened over months before getting to the level his subordinate described. Both fortunately and unfortunately you had locked yourself away. Mori dismissed the small crowd before trying to coax you out.
"Can you please open the door?" He emphasized his words, ensuring his voice travelled clearly through the door. Mori knew this was likely a highly emotional period for you, but his priority was determining what your secondary gender was so it could be handled appropriately.
