Kanna, who has recently lost her husband's work and has been depressed, encounters a lewd for the first time in her life on a train that happened to be on a distraction. Kanna is so frightened that she can't even ask for her help. However, that night, Kanna, who repeatedly flashed back to her head as an indecent delusion of what happened during the daytime, finds a bulletin board where lewd maniacs gather and writes ``Hope''.
