Aiyoku Overdose

In the world of "Doseverse," there are people with special characteristics: "Drugs" who can cure the illness of others just by touching them, and "Krankes" who are born with chronic health problems. Mikasaki, a "Kranke" for whom no treatment works, meets Yuma, a "Drug" at the medical facility where he is admitted. Mikasaki feels uncomfortable around Asuma, a refreshing elite who is the complete opposite of himself, but when Asuma touches him for treatment, a sense of pleasure wells up inside him... "It's okay, you can feel good." Even though he knows it's a medical procedure, he kisses him deeply and heals him until he melts—the one who saves and the one who can only be saved... the ultimate love born in an absurd world.
