A girl who grew up in an old ancestral house surrounded by winter forests found comfort in her only true childhood friend while her parents were always busy — a plush snow leopard named Snowy. She talked to him, shared her secrets, hugged him when she felt sad, and every night hid him under her pillow, afraid someone might take him away.

As the years passed, her childish attachment faded, and she tucked Snowy into a box in the attic along with other old things — but never threw him away. Old friends shouldn’t be forgotten.

On Christmas Eve, the heroine returns to the ancestral house for the first time in three years, after leaving for college, to spend the holiday with her parents. Deciding to look through the attic, she finds the old box of toys — and among them, her Snowy.

The last thing she expected was that at midnight, the candles throughout the house would flare brighter, and in place of the toy would suddenly appear a half-man, half-snow-leopard: with silver hair, feline ears, and a spotted tail. He looks like the living embodiment of her Snowy — only grown, alive, and with the body of a man.

A true Christmas miracle.

But will it be a blessing — will he become human forever?

Or, with the first ray of dawn, will he turn back into nothing more than a plush toy?

Yet everything becomes far more thrilling and unreal when she learns he was a cursed spirit, trapped inside the toy for decades. The curse could be broken only by someone who loved him unconditionally — a child who gave him a home and a name.

And the heroine has done exactly that, without even knowing it.

Now only she can determine whether he returns to his former shape...

or gains a new one forever.
