Fushigi no Kuni Shiro Usagi

Long before the destined heroine Alice ever appeared, a woman named Soyoon was pulled into the world of a reverse harem novel. She found herself in Wonderland, a lawless city teeming with criminals and outcasts, where she assumed the role of the White Rabbit—a messenger tasked with maintaining order among its dangerous inhabitants. Her only motivation for navigating this treacherous realm is a desperate hope: if she can guide the true protagonist, Alice, to bring the story to its proper conclusion, she might finally find her way back home to her family. The men ruling this chaotic world are far from ordinary. Heart is a sovereign who balances ruthless authority with unexpected gentleness, the Mad Hatter is a lethal serial killer, and the Twins are gang leaders fractured by split personalities. Yet, when Alice finally arrives, the narrative derails completely. Instead of fulfilling their intended roles as the heroine's love interests, these powerful figures refuse to follow the script. They orbit endlessly around Soyoon instead, their fascination warping into an intense obsession and blind devotion that threatens to unravel the very story she needs to complete in order to escape.
