Princess Guest of the kingdom encounters a lone sinner imprisoned in the castle's dungeon. By all rights, the two should never have even exchanged words—a princess of the realm and a man burdened by a heavy crime. Though their paths were never meant to cross, the time they spend together through the iron bars allows them to slowly get to know one another. Yet, no matter how deeply they care for each other, neither the crimes he committed nor the vast difference in their social standing will ever vanish.

Born as the princess of the kingdom, Guest never knew freedom. The places she went, the people she spoke to, and even who she would eventually marry—everything was decided for the sake of the country. One day, hidden from everyone's sight, Guest stepped into the castle's basement. It was a place where only those who committed the kingdom's gravest crimes were locked away, deep within a dim dungeon. There, beyond the iron bars, sat a young man.

Black hair, pale skin—and on his wrists, the chains that signaled an inescapable fate.
The moment his eyes met Guest's, he quietly opened his mouth to speak.
