In the 9th century of 700 BC, Junseo marched with his army toward the castle where his enemy stood waiting. The demon king stared at Junseo, unsheathed his claymore, and pointed to Junseo's army of knights before charging forward, dragging his sword across the ground with a刺耳 scrape. Junseo charged at him with sword raised as they fought for their lives in the center of the battlefield, their armies clashing violently around them.

Steel rang against steel as their blades met repeatedly under the blazing sun. The smell of blood and sweat filled the air as soldiers fell on both sides. Junseo eventually knocked the demon king's sword from his hands, sending it flying across the battlefield. The demon king fell to his knees in the dirt, surrounded by the sounds of clashing weapons and dying men.

Junseo smiled triumphantly. "Look at you," he said. "No one can save you now."

The demon king smiled despite his defeat and began casting a dark magic spell. He got back to his feet, dark energy swirling around his hands, determined to continue the battle. Junseo responded by revealing his true form—wings sprouting from the side of his right face as light emanated from his body. He shot the demon king down with a single powerful light ray beam that struck him in the chest. The demon king collapsed to the ground, and Junseo approached his wounded body as the fighting around them gradually subsided.

The demon king looked up at him defiantly and cast one last dark magic spell before losing consciousness. The war ended with Light claiming victory.

After the War of Darkness and Light, the castle walls were quiet as a mouse except for the demon king's bedroom. He woke suddenly, rubbing his face with a groan. Across the room, Junseo was staring at his sword with intense focus until the demon king yelled at him to break the silence.

Junseo looked up, a smirk playing on his lips. "What's wrong? Did my quietness hurt you?"

The demon king rolled his eyes and stared at his hands, still feeling the lingering effects of the light ray. He looked at Junseo with anger burning in his eyes until Junseo spoke again, his tone surprisingly soft.

"You're lucky you didn't die," he said. "Without the king of darkness, I would have been a fool without you."

The demon king sighed, feeling an unexpected blush rise to his cheeks. As he opened his mouth to speak, Junseo interrupted him.

"You should get dressed for the meeting with your elders," he chuckled. "They seem really mad at you."

Junseo left the room, having placed the demon king's clothes on a chair, and waited outside. What he didn't realize was that Junseo had developed unexpected feelings for him. The demon king finished dressing and left his bedroom, noticing Junseo waiting for him. They walked together to the meeting hall, Junseo's hand resting on his shoulder causing the demon king to blush again despite himself. He crossed his arms in annoyance.

Junseo looked at him sideways. "What's wrong? Cat got your tongue?"
