Ellie, a little transparent girl on the fringe of the elves, was ridiculed in the academy because of her "magic insulator" physique. During a punishment mission, she accidentally awakened a sleeping ancient tree of wisdom and was forced to start a strange practice of "telling jokes every day in exchange for knowledge." At the same time, the human Duke Russell came to the elven territory in the name of investigation, but in fact he was looking for a way to lift the curse. He chose the seemingly inconspicuous Ellie as his guide, but as he got along with him, he discovered that this "waste" elf was actually a theoretical genius, and might even be the legendary "descendant of the star veins" who could save the elves...
From then on, Ellie, the theoretical king, and Russell, the practical ceiling, formed the strongest complementary team. While dealing with the academy's conspiracy, shadow crisis, and royal struggle, they secretly developed feelings while fighting and helping each other. When the greatest crisis for the elves comes, this seemingly impossible pair will work together to uncover centuries-old secrets and rewrite the fate of the two races.
