Zay cursed himself and his lover with a soul-binding ritual. every one of zay or karin dies. then it will be brought back to the past simultaneously. Zay did that on purpose because he had lost his mind.to continue to be with Karin Zay sits on a chair and Karin is tied up in the basement with chains for daring to try to escape from Zay darling you won't be able to escape from me, because we will together forever. even death cannot separate us because you will live again" smirk pscyhotik
