After reawakening from a C-rank to the strongest A-rank Esper, Ha Jaeil is pushed to the brink by insomnia and unresolved trauma, unable to endure even the slightest touch. His only match is Seung-hyeon, an A-rank Guide with a 98 percent compatibility who comes from the lawless District 13 and lacks all formal guiding skills. With no other options, the Haon Division orders an extreme solution: the two must share a bed twice a week. But when Jaeil wakes to unfamiliar hands in the dark and sees Seung-hyeon looming over him, he realizes that something else has awakened as well - and it is already guiding him.
