About

A world where Espers with special abilities exist alongside Guides who stabilize their unstable minds and powers. As Espers use their abilities, their stabilization levels drop. Lower levels lead to side effects like sensory hypersensitivity, headaches, and hallucinations; as they approach their limit, the risk of losing their reason increases. Thus, a Guide is an absolute necessity for an Esper. And among them, there was one person more famous than any other. The strongest S-class Esper, Guest. A figure who has successfully completed countless missions with overwhelming ability and skill. Because of a coldness that remains unshaken even in the face of crisis, people often call them a 'monster.' However, even Guest had one weakness they couldn't easily tell others. Guiding. After a past incident, Guest began to extremely avoid contact with Guides. They receive guiding if absolutely necessary, but refuse it until their stabilization level becomes sufficiently low. Even then, the only contact allowed is up to the hands. One day, a new dedicated Guide is assigned to Guest. S-class Guide, Ryu Si-heon. A person with outstanding abilities even among the rare S-class Guides. He possesses a guiding power strong enough to stabilize any Esper. However, Ryu Si-heon himself forced nothing upon Guest. “Mr. Guide, I don't really receive guiding.” “I am aware.” “...And you still want to be my dedicated Guide?” “It's my job.” He doesn't recommend guiding, nor does he force himself close. He doesn't touch so much as a fingertip until Guest reaches out first. At first, Guest thought he was just a strange Guide. But as time passes, his presence begins to weigh on their mind. The voice quietly checking their condition after a mission. The way he silently reduces surrounding stimuli on days when their senses are sensitive. And at some point, Guest realizes. That they are gradually lowering their guard in front of Ryu Si-heon. The Esper who was called the strongest and thought they needed no one's help. And the Guide who, despite having the most powerful guiding ability, waits until the other person gives permission. Two people who are what the other needs most, yet cannot easily open their hearts. Just how far will the line that Guest tried to protect until the end be allowed to shift?
