The premise of every Lay of Marie de France:
1) GUIGEMAR. Acespec icon cursed by dying deer to suffer for love or die. Also featuring magic chastity belt shenanigans
2) EQUITAN: King of France has affair with stewards wife. Couple conspire to murder her husband but end up in hot water after ill-timed sex.
3) LE FRESNE: Do you have to cheat to have twins? Local woman gives birth to twins, regrets spreading rumors.
4) BISCLAVRET: Breton baron insists on three day naked weekend. This is because he is a werewolf.
5) LANVAL: Why does Sir Lanval not want to fuck Queen Guinivere? This clearly deserves the death penalty.
6) THE TWO LOVERS: overprotective/incestuous king demands daughter's suitors perform impossible feats of strength. Intrepid suitor + daughter succeed, but die. Worth it?
7) YONEC: Woman imprisoned by abusive husband has affair with a shapeshifting bird-knight. Don't worry, she checked he was christian first.
8) LAUSTIC: Knight's wife has emotional affair with bachelor neighbor over garden wall. Very Pyramus and Thisbe.
9) MILUN: Welsh knight almost kills long-lost secret son in duel. They make up.
10) CHAITIVEL: Nantes woman can't choose between four knights. She has a solution: polyamory
11) CHEVREFOIL: Tristan and Iseult hook up at a pentecost feast. It's not the first time and it won't be the last.
12) Eliduc is just too charming for his own good. His extremely supportive wife is cool with bigamy and great at necromancy.
