Uiko, a latent Omega, lives under the guise of being a Beta to to protect herself from the Alphas that are attracted by the Omega's pheromones.
Until one day when Uiko suddenly went into heat and couldn't control her pheromones, so she rushed to "AΩ", a salon for arranging anonymous one-night stands between Alpha and Omega!?
There, she met a mysterious Alpha behind a mask. Even though they had just met for the first time, he smelled sweet and made her insides melt, and their bodies were drawn to each other...
Now she wanted more, to want him back inside her body! What was this feeling that couldn't be suppressed even though it was only her first time?
