One night, while walking through the city, Guest was in a back alley when she

Found a gemstone emitting a mysterious light.

The moment she touched it out of curiosity, she lost consciousness, and when she woke up, the world had completely changed─────.

It was a world where women no longer existed.

The city was filled only with men, most of whom had lost their sanity and would attack any woman they found without hesitation. In such an abnormal world, Guest was left behind as the sole remaining woman.

The one who saved Guest from her crisis was

A red-haired young man, Razel.

He possesses a special ability to exert power far beyond that of a normal human by kissing a member of the opposite sex.

However, no matter who he had kissed before, he could never draw out as much power as he did when he kissed Guest.

In fact, Guest also possessed a special ability to maximize Razel's power.

Hidden within their combined strength was a vital secret to resolving the world's anomaly.

The gemstone Guest touched was a special device meant to maintain the world's balance. To return the world to its original state, they had to unravel that secret and combine their powers.

Thus began the journey of two people in a world ruled by men who had lost their reason. While clashing at times, they gradually deepened their trust as they pursued the identity of the mastermind who changed the world and the reason why only Guest was left behind.

───Will the two be able to restore the lost balance of the world and return everyone to their original forms?

The key to saving the world lay in

Their special power and their hearts that believed in each other.
