The Nerd Next Door Turned Out to Be the Magic Tower Master

Just before graduating from graduate school, the protagonist transmigrates into a world that she initially believes is a romance story. Determined to enjoy the dating life she missed out on while studying, she sets her sights on her neighbor—a beautiful man who is unfortunately a shut-in that refuses to take off his robe. As she pursues him, she discovers he is likely the same person as the infamous, psychopathic Master of the Magic Tower who obsesses over her, filling his room with her pictures and articles. However, these peculiarities become the least of her concerns when she realizes the world is actually a deadly horror survival game, not the romance she anticipated.
