Every year, just one girl from all high schools in Japan is chosen to be a “Princess”. Top high school boys from all around Tokyo are then selected to be the participants in a confession tournament that is Tokyo Yamanote Boys. It’s a love royale where the boys will confess to the Princess with various kinds of appeal. The one she picks will be crowned “Prince”, and there’s a legend that the Prince and Princess are guaranteed to have an eternally happy future together through this event.
