Saikou no Shousetsuka

Kurata is a talented editor with a string of successful projects under his belt. At a party, he finally gets the opportunity to approach best-selling author Enjouji Nao, whom he has admired for years, hoping to become Enjouji's new editor. However, Kurata is taken aback when he meets a strikingly handsome man who looks more like an actor than a writer. Despite Kurata's enthusiasm, Enjouji bluntly tells him that he has no intention of writing any more novels. The reason? Enjouji harbors a twisted tendency—after finishing a manuscript, he gets so sexually excited that he’s driven to attack anyone nearby...!
