Helping his classmates is an unlikely assignment for Hachiman Hikigaya, who dismisses the idea of a happy youth as a lie people tell themselves. Yet an essay ridiculing modern social relationships earns him an unusual punishment: his teacher orders him to join the Volunteer Service Club.
The club supports students seeking help with their goals, and its only other member is the cold, beautiful Yukino Yukinoshita. Working alongside her puts the apathetic Hachiman directly in the path of problems he never expected to handle. The two apply their wits to their classmates' requests, while Hachiman's deeply cynical outlook remains an open question: will it obstruct their efforts, or offer a useful way to approach them?
