Overview:

Jiwoo has supernatural powers that let her become invisible once a day when holding her breath. One day, she is taken to the police for stealing from a convenience store and meets Minsung who can teleport once a day, Hajin who can fly, and Kim Gongik, the mind-reader. But they all say they couldn’t use their powers that day. Did they bump into each other by chance? Why couldn’t they use their powers that particular day?
