As a reincarnated soul, Julius finally decided to have a proper romance. All he had ever wanted was a quiet life: going to bed early, getting up early, and never having to do homework. But then the blue-haired girl Shuang held out her hand to him. "Julius, would you leave this place with me? Become a couple and roam the world together?" After that, his parents sent a messenger with an invitation. The silver-haired girl Shiori said, "I won't treat you like my brother." Later, his classmate Reina said, "You're impressive, so I'm going to conquer you!" And so, in the world he had been reborn into, Julius met one girl after another. But life was not that simple. In this world of swords and magic, all sorts of things were about to happen.
