Colette is an accountant who works in the common people's tax department in the royal capital. She is demoted by her boss and becomes the personal treasurer of Prince Ladis, who is rumored to hate people! Although she reluctantly accepts the offer for a limited time, she hears from the prince with a devilish smile that he is looking for a child who snuck into the castle ten years ago. That's me, right? Will I be executed if I'm found out?! I don't want to die, so I'll quit being the prince's treasurer before anyone finds out!!
