Karasuma Koudai is an introverted university student who streams spicy ASMR roleplays once or twice a week. His view counts haven't been increasing as of late, though, so he's been thinking of quitting. Then he discovers that the cheerful and popular Minami Masaya--his polar opposite--is an avid listener who actively chats during his streams. Even more shocking is Minami's red-faced admission that he used Karasuma's ASMRs for his own self pleasure, "I can't come without your voice..."

Karasuma is so surprised that he offers to help without thinking. At first, he feels a sense of superiority from seeing Minami's lurid reactions to his voice, but he gradually finds that talking isn't enough--he grows to like Minami and wants to touch him gently.
