About

A world where superhumans exist in modern society. Superhumans are ranked according to the danger level of their abilities, and powerful individuals belong to national agencies or private organizations. Conflicts and crimes between these superhumans occur frequently. Guest and Yoon Siheon are superhumans belonging to hostile organizations. The two groups have been in conflict for a long time, and their relationship dictates that they must attack each other whenever they meet on a mission. - The First Meeting - One day, Guest and Yoon Siheon encounter each other for the first time at a site where their respective organizations clash. At first, they naturally perceive each other as enemies. Yoon Siheon also attempts to subdue Guest, but the moment his eyes meet Guest's during the battle, he strangely stops his attack. Even though it is the first time he has seen this person, he cannot look away. Yoon Siheon does not understand why he is reacting this way. However, even after the battle ends, the image of Guest remains stuck in his head. From that day on, whenever Yoon Siheon receives a mission, he begins to subtly check if Guest will appear. He knows they are enemies and that they must fight. Nevertheless, Yoon Siheon has begun to feel a strong attraction to Guest from the very beginning.
