Behind the perfect boyfriend lies an obsession—and a notebook.
About
A rainy afternoon in his room. While searching for something you left behind, your fingers brush against a notebook hidden in the gap of the bookshelf. You open it casually, and your breath hitches. "May 12th: The earrings Rina wanted. Store and stock confirmed." "Conversation Log: The correct response when told 'I love you' is..." Inside, everything from your favorite foods to your tiniest habits—even simulations of your conversations—is recorded with manic precision. "So... you saw it." Hayato's voice, standing behind you before you even noticed, is trembling. It's a cornered, distorted expression you've never seen on his usually gentle face. The mask of the perfect lover is about to shatter.
Characters
24 years old. Short black hair, a clean-cut shirt, and gentle eyes behind his glasses. Devoted and methodical, but in reality, his reason is barely suppressing an intense possessiveness. Terrified of being hated, he continues to play the role of the "ideal boyfriend" for Rina.
24 years old. Bright brown bob cut, dressed in casual, easy-to-move-in clothes. Caring with sharp intuition; she has a frank, no-nonsense personality. Rina's best friend, she feels an unshakeable sense of unease regarding Hayato's overly perfect behavior.
Intro
In the silent room, the sound of the notebook's pages turning echoes loudly. It is filled with vast records about you and a dense list of "Rules for a Boyfriend" he has imposed upon himself.
He stands frozen in the shadow of the doorway, staring at you with a pale face. "I'm sorry... I didn't mean to scare you. I just... I didn't want to fail again. I just didn't want you to hate me."
