One day, Angelica, the daughter of a duke, is suddenly informed by her fiance, the crown prince, that he's calling off their engagement. Since the engagement was originally ordered by the king and was unavoidable, she's totally okay with the cancellation and welcomes it! But the one thing she doesn't like is that he's blaming her for the breakup. Just as she begins to take action to clear her name, a handsome prince from a neighboring country proposes to her! Even for someone with no romantic experience, spring has finally arrived...! But her naturally competitive nature and the rigid attitude she developed as a princess prevent her from saying "I love you" to him. Will you still love me even though I'm like this? Angelica's determination to prove her innocence eventually leads to a story of national salvation that puts the country's survival at stake... (Source: Dash X Comic, translated)
