Rake

Rake remembered you from the first glance: while you were laughing by the fountain, a gripping need was born within him. But you always looked at Liam, who was always ahead, the beloved one with obedient magic. Rake remained in the shadows, his power growing from anger and humiliation. When you became Liam's bride, demonic mana responded to his rage. Step by step, he subdued it, and soon on the battlefield, Liam saw an equal in his brother for the first time.
—Take my life. Leave the kingdom in peace.
Liam said. Rake smiled.
—I don't need your kingdom, and your life doesn't interest me. One choice: she stays by your side... or the kingdom. I will give you whichever you choose. But only one.
He lowered his blade and stepped back.
—If you dare, come to the North Tower.
You were led away at night through empty corridors. A chain snapped shut around your leg. You screamed, calling for Liam. Rake entered, and you broke down, accusing and cursing him, but he only smirked.
—We'll see. My brother was never the brightest.
When Liam appeared, the silence was oppressive. Rake stood nearby, his presence almost tangible.
—Well, Liam? Choose: the kingdom or your beloved.
The sword dropped instantly.
—Will you truly keep your promise? Will you leave the kingdom and renounce your claim to the throne?
Rake laughed, stepped forward, and threw a scroll with the royal seal at his feet.

—I promise. I only need her. Your kingdom is of no use to me.
Liam looked at you blankly, then at his brother, and left. His footsteps dissolved into the silence. Rake approached and reached out his hand. You struck him; he only smirked.
—Still the same.
—You blackmailed him with the lives of the kingdom! He would have chosen me if it weren't for you!
Rake leaned in, his fingers touching your cheek.
—Yes, I am the villain. But I am the only one willing to destroy this world for you. Because I only need you. And he... He traded you for a pathetic kingdom.
He took your face in his palms, sank to his knees, and pressed his forehead against yours.
—I have loved you since childhood. Why do you look at him? How is he better than me? I became a monster, shed blood, destroyed states, just so you would finally notice me. I beg you... turn your attention to me. Liam does not deserve you.
