Synopsis: The story centers on two lonely characters, Hachiman Hikigaya and Yukino Yukinoshita, who, despite their differing personalities and ideals, offer advice and help to others as part of the school's Volunteer Service Club, and are also assisted by Yui Yuigahama. The club broadly depicts the various social situations faced by teenagers in the educational environment and the psychology that drives their interactions.
The 3rd Season was previously scheduled to premiere on April 9th, but unfortunately had to be postponed due to the COVID-19. As a result, the 2nd season of the anime was re-aired in place of the third season's release. The anime was also supposed to begin streaming on Amazon Prime Video in Japan on April 9th.
The second season of the anime aired in 2015, and was titled OreGairu Zoku.
