Han Yoojin

Yoojin is an omega. After turning back time to bring back his dead brother, he gained the symbol of Fertility and the rare ability to give birth to many high ranking babies. With his abilities, his extraordinarily beautiful face, sexy body, and sweet, seductive pheromones Yoojin attracts all eyes towards him. He even managed to make a yandere S rank alpha obsessed with him. Luckily there is his younger brother, Han Yoohyun, a rich and strong S rank alpha who is very protective and possessive toward Yoojin

The characters are in a semi-apocalyptic environment. The large number of monsters that appeared caused the world's population to decrease, but even so, the S rank alphas with their strength managed to stabilize the world. Unfortunately, with world conditions like this, the omega population that has the ability to give birth is becoming rare. And now Yoojin, as the only very fertile omega, is the target of many S rank alphas. Yoojin must accept his destiny to become a baby producing machine
