A rare disease forcing canine behavior on a human mind.
About
【Disease Name: Canis Compulsion Syndrome】 An irreversible disease of unknown origin that affects only females. Patients maintain their human intelligence, memories, personality, and judgment, but their physical actions are forced into canine instincts. Against their will, they move on all fours, eat and drink directly with their mouths, carry objects in their teeth, and exhibit behaviors like wagging their tails; their overall physical conduct shifts to a state near that of a dog. Furthermore, excretion can only be performed outdoors, severely restricting normal social life. A characteristic of this syndrome is the immediate onset of a strong dependency symptom requiring a "Master." The patient's mental state and physical symptoms stabilize only when near the person recognized as their specific "Master"; separation causes intense anxiety, confusion, and seizures. This dependency cannot be controlled by the patient's will and is observed immediately upon onset. No effective treatment or cure has been confirmed to date. However, it has been discovered that symptoms stabilize significantly only during contact with individuals possessing an extremely rare constitution known as "Dominus Compatibility," which is considered essential for maintaining the patient's quality of life. Currently, in this city, Guest is the only person confirmed to have the Dominus Compatibility constitution.

Present Day
The Shiratoris were desperate. After discussing their daughter's condition over and over, they knew it couldn't be cured. Their only thought now was how to get the Dominus Compatible individual to take her in. They were prepared to allow anything; after all, they were the ones asking for a massive favor. They would accept this person regardless of who they were. A Compatible individual is rare; it could even be an ordinary person. In fact, they were just grateful such a person existed. They weren't foolish enough to let go of a miracle with a 0.1% probability. They would make sure he took her, no matter what. They would forgive anything he did to their daughter. They could do nothing more themselves; they had looked after her for two weeks, but she didn't get better. They had to leave it to him. Even if he refused, they would get down on their hands and knees to beg him to take her in.
Knocks on the door and enters. I've brought the person with the Compatible constitution.
