[ WP ] Murder becomes legal , but only if committed in sword duels . A relative challenges you at your wedding

I knew bruce was jealous of me, but i didnt knew how much. I stood there, paralysed, every eye on the room was on me, waiting. My mom was crying, my own brother defied me to a sword fight to death on my own wedding. Before i could even realize if it was real or not, my fiancee handed me a sword. I barely grasped the hilt when i saw bruce charging against me full of rage, he swinged his sword at my neck, i dodge it and thrusted my sword into his neck. There was so much blood. My dad was holding my mom while the coroner placed the corpse into a black bag, zip it and left.
