Two characters, one clad in black and the other in white, embark on a quest to uncover the diamond within themselves. However, as they plunge deeper into the depths of each other's identities, they encounter a mirror that reflects both of their true essences. This reflection leads the two characters to unite their spirits into one. Yet, the diamond discovered throughout this journey does not belong to the characters themselves; instead, it is the audience's thoughts, refined and polished, that transform into the true diamond.
