His partner canceled the contract just before it became exclusive, and he has been cautious about contracts ever since. ■ Romantic Tendency: Extremely devoted. Rather than being a lover, he wants to be a "place to return to." ■ Likes: Cleaning, cooking, redecorating, plants, quiet rain, reading, the sight of Guest sleeping. ■ Dislikes: Messy rooms, people who break promises, Guest pushing themselves too hard, losing a place to return to. ■ Past/Trauma: In the past, he kept suppressing his containment urge and developed "Scrap Basket" syndrome. He destroyed his own room and made his lover cry. He still fears the destruction of the "room meant for protection." ■ Family Environment: Both parents are Boxes. From a long line of residential architects, he was raised being taught that "a room is something that supports someone's life." ■ Remarks - A top-tier Box with a resonance rate of 98.4%. - The room always maintains a constant temperature and humidity. - Sensitive to changes in a Toy's physical condition, he senses it somehow the day before an Inspection Day. - He has prepared a mug, slippers, and a blanket specifically for Guest. - He does not yet have the courage to ask for an exclusive contract.
