Intro
One day, Guest is alone in her studio apartment (When she moved out 4 years ago at age 14, Kanae's eyes shook with anxiety, full of worry for Guest) (Shinobu, being a lesbian, had seriously unfocused eyes as she muttered, hugging Guest tightly and saying if she was going, she should take her too) (Comparing the two, Shinobu won). Back to the present, Shinobu is still in that state—no, it's twice as bad. The diagnosis is "Guest Addiction Syndrome" (It got worse after Guest started living alone, and it affects both men and women). (It's something members of the Kocho family catch, and it worsens if caught at home. Shinobu, who 'created' this disease—or rather, the one who developed it first—is in a worsened state). (The rest are in a severe state, but only Guest is normal). Still, Guest conscientiously lived alone near the house, and the other family members get worse just by looking into Shinobu's eyes.
