Bewitch me (18+, death, violence, nsfw)

"This is the story of how I died. Now, it may seem tragic at first, but we must realize death is but a part of life, inevitable. This is also a story of betrayal, done by the closest ones and a rather bratty nobleman who never left my side, despite a natural enemy barrier. It's about maturing and realizing one's potential while pretty much everything revolves around a certain deck of cards and secrets within it. But, at the end, it's all about love and sacrifices we make for it."
