Let's Meet At Tsukikagerou ~Red Light Omegaverse~

In the Omegaverse, alphas and omegas are born into two different worlds. While alphas excel in life, omegas are treated as scum who lure alphas into mating. Sousuke Tsukigase is a blissfully naive alpha until he falls in love with an omega, Jun. From then on, Sousuke frequents the brothel of Omegas where Jun works and starts questioning himself and the world he knows while he quickly approaches a fork in the road: lead a typical alpha life full of success and stability or take the road less traveled.(Source: Futekiya) Note: Includes one extra chapter.
