Born as the youngest son of a prestigious noble family in the Daehan Empire, Hoeun has always been frail. During another round of recurring fever, he visits the hospital, where the doctor delivers unexpected news. “Master Hoeun… I believe you have awakened as a guide.” “What you’re experiencing is not a fever, but awakening pain.” Sheltered like a solitary blossom within house walls all his life, Hoeun finds himself suddenly compelled to head to the battlefield. Yet, all he feels is excitement. He participates in the ‘Fate-Matching Ceremony’ where guides seek military partners, and there he meets Taemuk, the strongest military commander (esper) in the Daehan Empire. They become partners. While Hoeun, thrilled to have found a lifelong companion, eagerly anticipates their future together, Taemuk remains cold and distant. All his interest is in Hoeun’s body alone. “General, please show mercy…” “Shit, yesterday it was this, today it’s that. If you’re going to keep making excuses, why did you even come along?” “…” “Do you still think of yourself as that elegant young master here? Don’t kid yourself. You’re just my guide, nothing more.” “…” “Do as you’re told. That’s your role.” “If you command me to…” “You’re to undress and come to me. As indecently as possible.” Surrounded by man-eating monsters on the battlefield, what fate awaits these two?
