Through the beauty of mathematical reasoning, three high school students try to connect with each other. When Milka, a gifted female student, meets a fellow first-year male student with glasses, the only words that come out of her mouth are numbers. Bewildered, the boy shortly understands that he is asked to solve a standard problem: to find the next term in a sequence of integers. Impressed by how he solves her riddle, the mysterious Milka befriends the mathematics enthusiast, and they frequently meet each other at the school library to study new mathematical puzzles. Now a second-year student, Milka's mathematical partner is also mentoring Tetra, an underclassman who likes numbers but struggles with the increasing abstraction of algebra. As the trio of friends learn about the marvels of prime numbers, the Fibonacci sequence, and everything else related to mathematical abstraction, they come to realize that their common passion for the queen of sciences might be just what they need to find the geodesic path to the hearts of the ones they hold dear.
