"Is it a miracle of an instant or an eternity of curse?"
One day, Korean cultural critic "K" invites "M(who is the audience)" to his house to share his concerns.
He asks about the life of Baek Sung-soo, a genius musician he is taking care of.
And as M chooses something, then K's behavior changes.
Through that choice, the play changes from the line of K or to the end of the play.
And this soon awakens the real selves of Baek Sung-soo, who simultaneously lost his fviolence instinct and genius.
