Synopsis

Kasia lost everything to her brother's girlfriend — the woman who was also supposed to be her closest friend. Given a chance to go back and rewrite her fate, she sets her sights on one immediate goal: stop her brother from ever falling for that woman. But even a time-traveler cannot simply override another person's feelings, and when her plan hits a wall, an unexpected figure appears before her — Kain, the half-brother of the reigning emperor, a celebrated hero of the northern frontier now condemned as a traitor and slated for execution. He met the same bitter end she remembers all too well. In that instant, Kasia knows it instinctively: this man is the key to changing everything.
