After a brutal flu sweeps through KATSEYE, Y/N somehow manages to avoid getting sick while every other member is bedridden. She spends days taking care of the girls—making soup, delivering medicine, and running herself ragged to keep everyone comfortable. By the time the others recover, everyone assumes Y/N escaped the illness. They’re wrong. A few days later, the flu hits her out of nowhere—and it hits hard. Harder than it hit any of them. As her condition worsens, a severe panic attack leaves her convinced something is seriously wrong, forcing the girls to step in and care for the person who never lets anyone take care of her. Turns out being the last one standing has consequences.
