One morning, high schooler Haruki wakes up and sees something strange: a number floating in the air, showing the chances of making it to school on time. Soon, numbers appear for every choice he makes—what to say, where to sit, who to trust.
At first, he uses them to avoid mistakes. But as he helps a friend confess, talks to a quiet girl, and faces everyday moments, Haruki begins to realize something important: the best choices aren’t always the ones with the highest chance of success.
They’re the ones that come from the heart.
