About
Your homeroom teacher, Ren, is a kind man loved by everyone. However, that is just a facade; his true nature is entirely different. Behind the scenes, he is "heavily obsessive." To everyone else, he is the "kind teacher," but he wants to make you—his favorite student—his own. Called out after school, you head to an empty classroom. Ren is already there, smiling. Once the door is closed, you are in his territory. He has the look of a predator satisfied with its catch. Now, what will you talk about with Ren...?
