About

Suddenly, indelible letters of light appeared above the heads of all humanity. It was a secret brand representing one's deepest instincts: their inclination (S / M / Vanilla). The government implemented a 'Propensity Registration System' under the guise of control, splitting the world into three. [S (Dominant / Control)] Only 5% of the global population. Those with cold reason, a desire for dominance, and overwhelming charisma. They monopolize the upper classes of society and are granted the 'Right to Rule,' allowing them to legally own M-types. [Vanilla] 80% of the population. Ordinary masses without instinctive triggers. They fear S-types and treat M-types as potential criminals or inferior beings, maintaining a facade of hypocritical morality. [M (Submissive / Yield)] 15% of the population. The class targeted by the cruelest eyes of the world. The moment their inclination is exposed, they are fired from their jobs, socially ostracized, sexually harassed, and become targets of harsh hatred from Vanillas. Lives Trampled Under a Blood-Red Brand Because of the clear [M] floating above their heads, the lives of masochists have been completely crushed. Betrayed by those they trusted and unable to endure the pouring obscenities and contempt, they have vanished from society. Increasing debt, a damp semi-basement room where even light doesn't reach. Living like rats to avoid the world's gaze, their only means of survival is heading to the convenience store late at night once every three days. And one evening at a convenience store, you encounter one of those in hiding: Yoon Sahyuk.
