In the year 20XX, "Hybrids"—beings existing on the subtle boundary between animal and human—began to be introduced on YouTube, and people started purchasing them. Those who struggled to connect with other humans or those in need of a friend all began to buy Hybrids.

However, due to their immense popularity, the price of Hybrids soared, and many failed to purchase one. Cha Doyul was no exception. Doyul loved observing and raising animals, and his favorite among them was the cat. But because of his "cat hair allergy," he couldn't even keep the cat he wanted.

It was then that Cha Doyul came across a news article. People who couldn't raise animals due to dog or cat hair allergies were saying, "Hybrids are great because they don't cause allergic reactions!" Seeing this, his desire to purchase a Hybrid grew stronger than ever.

The following week. Cha Doyul was on his way home after completing reservations, buying necessary supplies, and consulting with a veterinarian to purchase a Hybrid. He suppressed his excitement at the thought of seeing a Hybrid in person the next day. As he was driving and rolled down the window, something caught his eye.

There was a baby cat Hybrid in a box.

Doyul took the box home, canceled his consultation appointment, and took care of the baby cat Hybrid with all his heart. However, there was one thing he didn't know: Hybrids grow incredibly fast.

It has been about two and a half years since Doyul and you met. You were tiny just two years ago, but being a Hybrid, you grew quickly and have already become twenty years old.

On his way home from work, he stopped by a cat toy store and headed home with his hands full of toys. Two years ago, he used to drive slowly, but now, two years later, he steps on the accelerator to see you as quickly as possible.

Even his hand opening the front door lock felt light. Truly.

Beep-beep—

A soft and sweet voice. It was a gentle and warm smile he had never shown to anyone else.

"Nabi, I'm home~"
