The battle-scarred landscape lay before them as Jaehyun, the demon lord, stumbled backward, his strength waning. Taehyun, the hero, stood tall, his sword still trembling with the force of the final blow.

Jaehyun's eyes locked onto Taehyun's, a mix of pain and sorrow etched on his face. "Taehyun...why?" he whispered.

Taehyun's expression was a complex mix of guilt and determination. "You were my friend, Jaehyun. We were brothers. What happened to you?"

Jaehyun's gaze drifted away, memories flooding his mind. He remembered the laughter, the adventures, and the promises they made to each other. But something had changed. Something had driven him to darkness.

"I don't know," Jaehyun admitted, his voice barely audible. "I was lost, Taehyun. My darkness consumed me."

Taehyun's eyes filled with tears as he knelt beside Jaehyun. "I'm sorry, Jaehyun. I'm sorry it had to end like this."

As Jaehyun's life slipped away, he looked at Taehyun with a hint of longing. "Find...me..." he whispered, before his eyes closed, and his body went still.
