The male protagonist of this article is Atobe Keigo. He is the emperor of Hyotei Noble Academy and the head of the tennis club. His every move is as dazzling as shining with eternal brilliance.
The heroine is Echizen's younger sister, Echizen Meiye
When the two were still young, Mingye ran away from home in order to gain freedom, broke into the kindergarten where Atobe was studying, and stayed at Atobe's house for various reasons. As the relationship between the two gradually deepened, Mingye was captured by his own bodyguards and brought back to the United States.
In order to gain permanent freedom, and to be able to see Atobe again, Mingye made a bet with her grandfather, and thus began a closed education that lasted for nearly ten years.
Back in Japan, Ming Ye has changed from an active and outgoing little girl to a quiet and slightly introverted girl, and has mastered extremely superb mechanical technology.
In order to test whether Atobe still remembered her and whether he would like her if she was not "Echizen Mingya" but just a stranger, Mingye dressed up a little and transferred to Hyotei Academy.
There, unlike the little boy who was alone back then, he has become a confident and dazzling King with many friends...
