In a world where “espers” are treated so badly that they are called “monsters,” Seung-won, a class B esper, is unjustly accused of sexual harassment by the prodigal son of a tycoon family and demoted.
Seung-won, who has to take care of his mother and sister, is forced to accept a job as a bodyguard for an “S-class guide” during his suspension period.
However, the target of his protection, S-class guide Jin-ho, is a “rich kid” whom Seung-won detests, as well as a moody young man who hates physical contact.
Furthermore, Jin-ho, who persistently harasses Seung-won, seems to have something against him. However, Seung-won does not give up easily, and in the end, the two end up confronting each other.

Thus, even though they detest each other, the two end up becoming very close. But after that, Seung-won begins to have strange dreams in which a person very similar to Jin-ho appears...
