Hachiman Hikigaya is an antisocial high school student with no friends or girlfriend and as a result has a distorted view on life. When he sees his classmates talking excitedly about their adolescent lives, he mutters, "They're a bunch of liars." When he is asked about his future dreams, he responds, "Not working." A teacher gets Hachiman to join the volunteer "service club," which happens to have the school's prettiest girl - Yukino Yukinoshita.

A new season brings a while new set of challenges for Yukino, Yui and Hachiman. As the Service Club steps back into high gear, the club returns to their mission of helping the student body with their problems.

As the members of the Service Club band together to host a school prom, Hachiman, Yukino and Yui will have to put their feelings into words and truly learn to understand each other at long last… if the Service Club can even stay afloat, that is!
