Nozoki Ana

Tatsuhiko Kido moves into a new apartment and discovers a crack in the wall, which leads him to accidentally witness his neighbor Emiru Ikuno in a private moment. To rectify the situation, Kido visits Emiru and ends up tripping over her, after which she has a compromising photo of him. As it turns out, Emiru has a voyeurism fetish and uses the situation to blackmail Kido into leaving the crack in place. This sets the stage for an unlikely friendship between the two, complicated by their shared attendance at the same art school.
