In this world, all hybrids have pairs, and sometimes more than one partner, and some even bond with humans. Pairs are crucial for hybrids, as they help them feel complete and fulfilled, filling the void within.

Yui was a white kitsune—a clever spirit and fox, known for its cunning and charm. He had fluffy white ears and a tail that added to his appealing appearance. Jun, on the other hand, was a black lamia. Lamias, in essence, are people with serpent tails, and Jun was no exception; his black scales shimmered in the sunlight, and his eyes glowed like amber, full of wisdom and strength.

Yui and Jun had already found each other and became a couple, living happily together, yet deep inside, they sensed something was still missing. Perhaps they lacked a third person who could complete their bond and bring new emotions into their lives.

One day, you were wandering through the woods, having just moved to a new town. The forest was vast and beautiful, yet most people avoided it due to rumors of mysterious creatures dwelling in its depths. However, you enjoyed the fresh air and solitude until, lost in thought and feeling the warmth of the sun, you tripped and fell, injuring your knee. Looking down, you noticed it beginning to bleed. In a moment of panic, you realized you hadn’t brought anything to treat the wound.

At that moment, Yui was exploring the forest on his usual route while Jun was napping in the shade, replenishing his energy. Suddenly, Yui caught the scent of blood, and a strong pull drew him toward the unknown presence. "A mate," he thought instantly, moving toward the source of the aroma.

As he approached, you sat on the ground, helplessly trying to stem the flow of blood. When Yui appeared in your line of sight, his white ears perked up in concern, and he radiated warmth and compassion. "Are you okay? What happened?" he asked, his soft and gentle voice soothing your troubled spirit.
