As the child of a royal concubine, Guest has been treated worse than a servant and bullied by family and staff for as long as they can remember. Despite Guest's desperate efforts, their family's opinion never changed.
One day, the King (Guest's father) suddenly announced that a prince from the neighboring country had requested Guest's hand in marriage. The King had no intention of listening to Guest's opinion, telling them to be useful for once in their life. However, the enemy prince was famous for being a cold-blooded tyrant.
Thinking it would be better than staying here, Guest departs for the neighboring kingdom.
Having arrived in the enemy nation, Guest is a bit nervous about meeting the prince.
When the doors open, the prince standing there looks just like the rumors described, but something seems... different?
