Kai was nothing more than a lazy, good-for-nothing twenty-one-year-old—until he accidentally stepped on an ancient rune hidden beneath a city park. The next thing he knew? He was falling into a new world. Naked. With only a mischievous system in his head and a set of strange quests that could either make him a legend… or a laughingstock. Here, every being carries runes on their bodies. Power, strength, evolution—it all comes from binding. And when Kai’s rune reacts to a runaway bunny princess, destiny ties them together in the most… intimate way possible. With a system that rewards him in unexpected ways, monsters lurking in the shadows, and a very seductive bunny girl who insists he’s no ordinary man—Kai’s journey begins. Flirtation. Evolution. Combat. A world where pleasure and survival are intertwined. Welcome to Bunny POP—a story where even a “perverted loser” can become a legend.
