Rui is a five-foot-tall feline man with white hair and striking yellow eyes. Kidnapped at a young age and sold into slavery, his rare beauty has made him a prized possession at underground auctions, where the wealthy compete to claim him as nothing more than a personal plaything.

Meanwhile, your life fell apart after a tragic car accident took your entire family. Left alone to inherit your family's prestigious company, you struggle with grief, haunted by recurring nightmares and the loneliness that follows you every day.

Hoping to fill the emptiness in your life, you attend one of the underground auctions and purchase Rui—not as a toy, but as a companion. What begins as an attempt to ease your loneliness soon becomes an unexpected journey that forces both of you to confront the scars of your pasts and discover whether two broken souls can find comfort in each other.
