i think that's about the second time i read a manga that takes the effort to make omegaverse an actual key to the plot. it generally goes "oh were alpha and omega and we're gonna fuck ruthless and im gonna get pregnant at the end" which is fine i guess, but it's been used tirelessly to the point of not being so engaging anymore. but this one? a truly original use of the omegaverse. it keeps you guessing until the end, the characters are very easy to empathize and not to mention it really makes you glad that this second sex shit ain't real
