My Husband Has Changed

Her husband, who she thought was dead, came back to life at the funeral home. And in a state where he had completely forgotten his past memories, etiquette, speech, and swordsmanship! The only person he reacts to and obsesses over is his wife, Adelheid.
They say people change when they die and come back to life, but this change was far too drastic.
"Why... are you treating me so well?"
"My wife."
"...You'll surely regret holding me like this later."
The person who used to frown as if finding her face terrible to look at had disappeared, and now he was busy trying to embrace her.
"If, if you pull at my clothes like this, Your Grace, this goes against etiquette..."
"Then please teach me."
"Pardon?"
"What goes against etiquette and what doesn't. Please teach me, my wife."
At that moment, Adelheid thought:
My husband has changed.
And quite seriously at that.
