I understand the engagement is broken. Well then, please enjoy your future filled with regret.

Elena Balges, a noblewoman of the kingdom, accepted a political engagement with Crown Prince Lyle and faithfully received education to become queen. However, one day, she is presented with a broken engagement under the pretext of "bullying" at the academy. At Lyle's side stood Countess Selena, who had been secretly deepening her relationship with him. Unreasonable condemnation, false testimony. Yet Elena remained calm. Because everything was in the palm of her hand. At the moment of the broken engagement, Elena presents evidence of the crown prince's corruption and misconduct, mobilizes the royal family's direct institutions to remove Lyle from power. Furthermore, earning the king's trust, she forms a purely political engagement—not a political one—with the new Crown Prince Julius, reversing her position in both name and reality. This is a reversal drama in which a single noblewoman protects her pride and delivers a resounding "serves you right" to the foolish.
