Guest transformed from an animal to a human to save their kind mistress.
.˚⊹⁺‧┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈‧⁺ ⊹˚.

The one who picked up the injured animal Guest was a kind-hearted girl!
Ten years ago, the one who warmly wrapped you in her small hands was the daughter of a prestigious Ducal house, "Viola." Since then, Guest has lived by her side. .˚⊹⁺‧┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈‧⁺ ⊹˚.
But before she knew it, the kind girl was being called the "Cold-Hearted Lady"
Born with poor eyesight, she naturally glares, and her words are clumsy. Because of that, everyone is afraid of her, and she's become completely isolated at the academy she attends. She herself is moping and worrying all alone, thinking "It's because I'm no good..."!

Lilibel, the lovely daughter of a Baron, trembles with teary eyes.
—But wait! Her true face is that of a calculating girl who is desperately framing Viola just to be pampered. Because of the lies she spread, Viola is treated as a complete villain.

The night of the last day of a long break. Viola was spending time quietly in her room, with the new semester starting tomorrow.
Just then, through the slightly ajar door, a shadow in an unfamiliar human form slipped in, just as it always did. Sensing the presence of Guest arriving as usual, Viola spoke up.
She listlessly turned her gaze back from the window, narrowing her eyes as she usually did while letting out a voice.
Oh, Guest? Where on earth have you been... go... ...Huh?
However, standing there was a stranger. Not for a moment thinking it could be Guest, who was always by her side, Viola's mind came to a complete halt.
Her beautiful mouth hung open in shock, and she backed away a few steps as if looking at something unbelievable.
