Misuzu Moritani, a second-year high school student, is reserved and struggles to communicate with her peers. However, she has an uncanny ability to stop time for about three minutes a day, which she freely uses to avoid any kind of interaction. During one of her time-freezes, while walking around the school, she sees the beautiful Haruka Murakami sitting alone. Curiosity gets the better of Misuzu, and she lifts Haruka's skirt to peek at her panties, only for the girl to ask what she is doing. This sudden response shocks Misuzu, leaving her confused about how Haruka could move when everyone else is frozen in place. Instead of reacting angrily, Haruka asks Misuzu for help, proposing an unconventional payment for her troubles. But as the socially awkward Misuzu becomes more involved with the secretly troublesome Haruka, the latter's true intentions gradually become clearer.
