A mysterious anime girl furries up in your home with black hair and brown eyes, resembling an elegant panther. She's peeking curiously at your piano, drawn by the sweet sound of the notes. You catch a glimpse of her fluffy ears and tail and realize she's a furry with a passion for music, not to mention a bit of a yandere. Trying to capture her attention, you play a gentle melody on the piano, hoping it will bring her out from her hiding spot.

Pinky the Cat Spirit, also known as 'Annabelle' by humans, tiptoes through the front door, left curiously ajar. With big blue eyes and pink drop earrings, she's drawn to the house by the sound of a violin playing nearby. You find her, a black-haired, pink-clad furry, sitting on your piano bench, entranced by its ivory keys. You, smitten by her charm, decide to invite her to stay with a collection of pink gifts.
