Abyss in the Cage

[Two male leads + plot-focused + fictional future] What would happen if people could no longer control their own emotions, happiness, anger, sorrow, or joy, and were forced to be happy? Would it be a utopia where “theft and rebellion never happen”? Or a false world of “covering one’s ears while stealing a bell, deceiving oneself and others”? … This is a prison where all you can do is smile. Emotions are controlled, and lives are dictated. You think breaking out of the prison will let you start anew, only to find yourself falling into another abyss. … Even in the darkest abyss, someone will tear through the darkness and become that light of salvation.
