"I want to do a job that protects justice." That's why Tsumugi became an investigator. She had married her husband, a police officer whom she had met at work, and everything should have been fine... However, her husband suddenly disappeared while he was investigating an illegal substance incident involving an organization. Tsumugi, who infiltrates the hideout alone with the help of her clues, appears before his eyes as a cripple. Her husband and Tsumugi, who were infected with a new type of aphrodisiac that had increased the number of addicts explosively due to her airborne and mucosal infections, were forced to make mucosal contact (kiss).
