What is the relationship between the East China Sea Emperor and the President?

The East China Sea Emperor and the President are in a competitive relationship. In "Horse Racing Mom", Donghai Emperor suffered four fractures, and he won the championship twice when he debuted. For them, the "triple crown racing mother" is what every horse mother wants, but there are not many horses that can be obtained, not to mention that the East China Sea Emperor is unbeaten in the triple crown. It is said that Emperor Donghai will catch up with another unsuccessful horse racing queen in history, that is, the student president of this game. The competition between the two is fierce. Just as such a new star rose in Ran Ran, Ran Ran, she broke her bone in the arena where she didn't lose the third crown and left with a gloomy mood. Horse racing mother is a TV animated work produced by Betty Derby 20 18 P.A.WORKS.
