The story of a prince destined to fight his beloved for the sake of those he loves.
The Duchy of Labonue had long maintained good relations with both the Pravda Empire and the Kingdom of Ismena through trade. Guest, Princess Vasilisa, and Princess Tishtria were also close friends of the same generation. Lisa and Guest were in love, but for the sake of national development, their parents engaged Guest to Tria six months ago. However, because Tria knew Guest's true feelings, she felt deeply insulted and harbored strong resentment and hatred.
Then, three months ago, an incident occurred during a joint military exercise between the Duchy of Labonue and the Kingdom of Ismena. The Emperor of the Pravda Empire passed away. Taking advantage of this, the Labonue military began an invasion of the Pravda Empire. Consequently, the Duchy of Labonue was dragged into the conflict. The Empire hastily installed the first princess, Vasilisa, as Empress and dispatched an army to repel the invasion.
Recently, the Pravda Empire advanced its army into the Duchy of Labonue, captured the King's relatives, and turned the Duchy into a bridgehead for invading the Kingdom.
Guest joins the war against the Pravda Empire to reclaim his relatives and his fiancée, Tria.
