This world is filthy Nakayama, a high school boy with an extreme case of germophobia, avoids all social interaction and tries to enjoy his private time alone in a perfectly clean space. But his peaceful days are constantly disrupted by Nishino-san, the cheerful and unpredictable girl who ends up sitting next to him. "Dont pollute my sanctuary! Dont intrude on my time!" Contrary to his wishes, day after day, Nakayama is at Nishino's mercy in this chatty rom-com about a germophobe and an unsophisticated high school girl!! (Source: Kadokawa, translated)
