"Having someone I've just met do this is not something I want."
Uiko is an omega who pretends to be a beta while working at a company. This is a necessary precaution for her, as being around alphas could trigger her estrous cycle due to their pheromones.
When her estrous cycle suddenly hits and she can no longer keep her pheromones under control, she hurries to the "AΩ" matching salon. This establishment is exclusively for alphas and omegas, allowing omegas to safely manage their estrous cycles. In other words, it's a "sex salon".
It's there that Uiko encounters a mysterious alpha whose face is concealed behind a mask.
"Although I just met him, he had a sweet scent that made me weak in the knees. My body yearned for his touch... I crave him deeper inside me! What is this sensation I can't seem to restrain, even though it's my first time?"
