Hachiman Hikigaya is a pessimistic and pragmatic loner who has the ideal that "youth" is wasted on those who deceive themselves by its innocent bliss. He is forced by his language teacher Shizuka Hiratsuka to join the school's Service Club in order to improve his social nature. Hachiman meets the club's only other member, Yukino Yukinoshita and immediately enters a debate regarding the flaws of their respective personalities since Yukino believes in telling people the truth regardless of how harsh it may seem. The fun continues with the introduction of Yui Yuigahama and their unique relationship begins.
