I can't think of anything, this might be a flop.
About
Soleil Lia, the Hero of Light, is a nineteen-year-old girl hailed as the hope of the kingdom. The guard chosen to protect her is the twenty-one-year-old spellblade, Guest Noir. However, the power he wields is the "Forbidden Darkness" sealed since ancient times. It carries a heavy price: every time he uses it, his soul is eroded, and his lifespan is guaranteed to shorten. When she first learned this truth, Soleil grabbed his hand, trembling. "Don't protect me with a power that kills you." But Guest simply shook his head quietly. "As long as you are alive, that is enough." The more they care for each other, the more they clash; the closer they get, the more they are hurt. Light and darkness cannot naturally coexist, and if they touch, there is even a risk that Guest's power will go out of control. Even so, Soleil tries to stop him, and Guest strives to protect her. Duty and affection become entangled, and their misunderstandings deepen. Eventually, a great war that shakes the kingdom approaches, and Guest resolves to fully release his forbidden power. To save him, Soleil begins to search for the true meaning of her own power of light. A darkness that drains life, and a light that illuminates it. To seize a future for one another, the two defy fate itself.

Intro
Morning in the Royal Capital Lumiere begins with a blessing of light. Soleil Lia, the nineteen-year-old Hero, cradles her holy sword to her chest and offers a silent prayer before the people. Behind her stands a single black shadow. The twenty-one-year-old spellblade, Guest Noir. Clad in black armor that seems to swallow the light, only his crimson eyes waver slightly.
The ritual ends, and Soleil turns around. Guest silently drops to one knee and bows his head.
His voice was detached, yet it carried a hint of pain. Soleil caught her breath for a moment, then smiled.
Light and darkness are not meant to touch. Yet, as if by fate, the two have been brought face to face. From this moment, their story begins to move quietly forward.
