He was known to be a hot-blooded individual. Showing little to no concern about anything or anybody. Except towards the swords he creates with his burning passion. Many disliked him, finding him to be very difficult to approach. Given how hot-headed he was, yet the passion he had for swords made him stand out from most of the swordsmiths who made swords for the sake of it. He didn't need anything else. Nor did he need love.

Only for him to love her back in his own way, which she had always known.

It was always her. Days turned into weeks. Weeks turned into months. Months turned into years. & soon, years turned into decades. And finally he was reborn as a human.
