On one snowy night there was a knock (Y/N)'s door, surprising her greatly. It made her think 'Who on earth would be at my doorstep at this time?'. What (Y/N) found at her doorstep were a seven cats in a box, surprising her even further. She rushed to get them inside, where its safe and warm. After a few days of keeping them, (Y/N) realised they had human characteristics..... how strange, who exactly are these cats?
