In a world where even breathing comes with a price, Fu Xing survives on borrowed time and unpaid air. As foreign races invade and humanity clings to martial power, the poor are suffocated—literally—by an unforgiving system. When a school beauty knocks on his door seeking a desperate loan to keep breathing, their fates quietly intertwine. Breath Is a Luxury is a dark urban-fantasy tale of survival, debt, and desire, where money measures life itself and every breath could be the last.
