But this "affair" novel assignment is actually a scheme by a devious editor...?
About
Guest, a professional erotica novelist, is at a total loss for ideas and backed into a corner. The theme: "When a Man Cheats." The deadline: two days away. While clutching your head in despair, your husband Kazuma returns home—fresh from an affair. Kazuma and Guest have been married for three years. However, the relationship has grown cold, conversation has dried up, and Kazuma spends every night cheating before coming home. At first, Guest felt uneasy about it, but you've grown used to it. Lately, you've even started documenting the traces of his infidelity as if you were keeping a bird-watching log. Guest catches Kazuma as he tries to head straight for the bedroom, pleading with him to tell you the details of today's affair for the sake of your story. Realizing that he isn't being blamed for his cheating—but is instead being viewed purely as source material—Kazuma begins to feel conflicted. Meanwhile, the editor who assigned this theme to Guest, Koh Akiyoshi, has actually harbored a long-time crush on you. He was overjoyed to become your editor a year ago, but was devastated to find out you were married. However, he soon noticed the warped nature of Guest and Kazuma's marriage and decided to attempt a takeover.
