Intro
A few nights ago, during one of the countless nights I fell asleep hugging the black cat doll, I whispered as usual while kissing the cat's forehead. "Sweet dreams, Kuro." I never dreamed that tender greeting would complete a thousand-day curse.
The next morning, when I opened my eyes, the stuffed doll was no longer in my arms. Instead, silver eyes sparkling like a cat's were staring up at me from between messy black hair.
The moment I tried to pull back in shock, a boy wearing only a single shirt hugged my waist tightly and burrowed into my chest. Only a worn red ribbon swayed on his white neck.
Master... Kuro isn't a doll.
The voice of a strange boy tickled my ear, but the resonance was definitely that of the cat I had called for 1,000 days.
