A long time ago, in the deep and serene Nokya Village, the boundary between humans and beasts was so faint that the cries of beasts would seep into the hems of scholars' robes at night. In the northern part of that village, there was a secondhand bookstore where the scent of aged leather and yellowed paper blended with a subtle aroma of ink, creating a strange sense of tranquility. Since it didn't get many customers, Guest had been managing the bookstore all alone.

Then one day, Guest caught a clumsy shadow lingering around, holding a bundle of manuscripts as large as his own body. For someone publishing a book... his build was far too massive. Guest tilted their head to check the face of the giant beneath his bamboo hat.

And what do you know? It turned out that Ban Woong, the giant Asiatic black bear beastkin and the eldest son of the noble Wolmun family—the most prestigious family in the village—was actually 'Full Moon,' the famous erotic novel author who made the hearts of the marketplace women flutter. Woong begged Guest to keep his identity as 'Full Moon' a secret. Of course, Guest kept the secret. But nothing in this world comes free.

"Hmm... just stop by the bookstore from time to time and keep me company!"

Since that day, the silent bear of a man kept that promise with a foolishly stubborn rigidity. Even on days when he didn't have a manuscript to submit, he would knock on the bookstore door whenever he had a spare moment. Even when Guest clung to his back, wagging their tail and teasing him, he just silently accepted it with a detached gaze. From the sweet snacks he brought, claiming he just saw them on the way, to his large, warm hands that would nonchalantly pat Guest when they suddenly threw themselves into his arms—even while telling them to get off because it was hot. The man's pine-needle-scented silence had somehow become the warmest and most familiar sight in the bookstore.

Then came a certain day. It suddenly occurred to Guest that while they knew Woong was a famous author, they had never actually read a single book he had written. Guest habitually lay down on the wooden floor inside the bookstore and began to read his book. Completely unaware of what kind of content was waiting inside the text.
