His Dark Claim

"Why can't you let me go?" Her timid voice echoed through the walls of his heart and he heaved a deep sigh.
He couldn't. How could he? She was the air he breathed. Blood in his veins. It was so simple and yet he couldn't make her understand. How did their relationship end up like this? He loved her and she loved him, didn't she? Then why?
"I cannot do so, Dolcezza. I'll go crazy without you, you cannot leave me, I won't allow you to."
And she shook her head, a laugh-filled with disbelief escaping her lips as she struggled to unbind herself from the chains. "Then at least free me of them."
"No."
A love so vicious it binds. A madness so deep it consumes. Escape is an illusion, and freedom... a cruel dream.
For in his arms lies ruin... and in hers, salvation.

Zagreus didn't know what jealousy was until he saw the love of his life finding solace in the arms of a man he loathed with his guts. Admiring and keeping her safe from his world, he decided to not interfere in her life and started protecting her from a distance.
Until one day he found that the woman who was supposed to be his was dating his enemy behind his back. Love and care were replaced by raw anger and ravenous rage and he did what he thought he should have done initially. He claimed her.
