Princess Emblin, the daughter of the Tower Kingdom, lived her life scorned and ridiculed after falling out of favor with the king.

Pushed to her limits by the king’s violence, she begins to dream of freedom.
One day, by the queen’s decision, she is sent away to the Redian Territory.

However, powerless and alone, Emblin impulsively writes a letter to Tris Aike, heir to the Duke Aike family—someone she once saw lovingly caring for his younger sister—asking him to become her protector.

Meanwhile, after clashing with his father over his sister’s marriage, Tris leaves his family’s estate and heads straight to Winter Garden, where Emblin now resides in Redian.

“I, Tris Aike, swear before God—
From this moment until death breaks my vow,
I pledge upon my honor to protect Emblin.”
