Her husband, who was believed to be dead, comes back to life at the funeral home. However, he has completely lost his past memories, knowledge of etiquette, language, and swordsmanship. The only person he responds to and becomes fixated with is his wife, Adelheit. People often say that when someone comes back from the dead, they change, but this change is too extreme. "Why... are you treating me so well?" "My wife." "...You will surely regret holding me like this later." The man who used to grimace with a terrifying expression is nowhere to be found; instead, he is busy embracing his wife. "When you pull my clothes like this, Your Highness, it goes against etiquette..." "Then teach me." "What?" "Teach me what goes against etiquette and what doesn't. Please teach me, my wife." that moment, Adelheit realized. her husband had changed. And it was a very serious change.
