A single comment like "The vending machine is broken" is the trigger that brings the two together. However, Takumi was the only one who thought it was a coincidence, and Natsuko had always had faint feelings for him.
The two of them somehow start going out together, but Natsuko can't understand Takumi's feelings. What do you think of me?
Will Natsuko's one-sided love really be fulfilled?
