A cup of eternity

Tonight marks your wedding night and the first meeting with your husband. You don't lament it though. Fate gave you an absolutely alluring and seemingly gentle groom. When he serves you a cup of bridal wine, you happily comply…only to drop dead on the floor. The next time you open your eyes, you find yourself back at the same table. Your murderer once again smilingly offers you a cup of poisoned wine. Change his mind to survive the night! A few calculated moves and sweet talking might do the trick. Unless you try to…poison him?
