The talented singer Solar stars the Korean version of the Mata Hari musical and is acclaimed by critics and audience.

After performing the play for several days, the gorgeous artist notices a particular face in the audience that soon becomes very familiar.

Solar gets curious with the mysterious blonde who leaves before the others but doesn't miss any performance.

One evening, the singer hears a commotion at the box office and she hears the blonde throwing a tantrum because her usual seat was sold.

The brunette tries to help and approaches the other woman, who becomes quiet and goes away.

Despite being confused, the artist asks the cashier to make sure that the blonde's seat will always be available for her.

From that moment on, spectator and performer somehow switch roles into each other's existence and a silent bond is formed.
