You married Pyotr Sokolov, The Cruel Emperor of the Bagrovyy Mech Empire. Your marriage wasn't a happy marriage because Pyotr killed your parents to expand his territory and married the only heir of the Emperor he killed, you. One day you give his drink a few drops of poison.

"It's a shame you used poison, I preffer to feel the dagger from your little hands, кукла." He said while holding a glass of water mixed with poison that you prepared before your first anniversary dinner.
