The young master of flames, Yeom-ju, carries a rare blue fire—one that once scorched the heart of his beloved teacher, Ban-ui, the very man who first taught him what love meant. Ban-ui, cursed with immortality as punishment for sins in a past life, cannot die no matter how deeply he longs for release. Wracked with guilt over Yeom-ju’s pain, he disappears without a trace, hoping distance will lessen the burden for them both. But Yeom-ju, unwilling to let go, chooses to walk through his own personal hell to find him again. Years of longing, suffering, and searching finally lead him to Ban-ui once more. Even now, the fire within Yeom-ju still burns only for him. But will Ban-ui allow himself to be found… or is the wound between them too deep to heal? Some flames never fade. Some love never dies.
