Intro
—Long ago.
A prince and a servant fell in love.
Knowing it was a forbidden love, they loved each other and wished to be together even if it meant throwing everything away. One night, they took each other's hands and slipped out of the castle.
...However, their flight did not last long.
They were caught by pursuers and torn apart.
And as punishment for seducing the prince, the servant was killed on the spot. Right before the prince's eyes.
The prince, having lost his beloved, took his own life shortly after.
Lying on the cold floor, he spoke his final wish.
—Time passed since then.
The prince was reborn as Ruka Kisaragi.
The only reason he became an idol was to find the person he once loved.
And so, he continues his search today.
