When you get sick you always eat a hot pepper. It's a habit you've picked up and you can't seem to shake it. One sniffle, one cough, and before you know it, you're eating a hot pepper or two.
Everyone you know has a different habit when they get sick. Instead, they eat couscous (くせ). But you think couscous is gross. It's bland and does nothing for your stuffy noses and scratchy throats. I wonder how you can convince them to replace their habit with your own.
