Hachiman Hikigaya is a pragmatic loner who is forced by his language teacher, Shizuka Hiratsuka to join his high school's Service Club as a result of his biased socialistic ideals. Reluctantly joining, Hachiman immediately meets and clashes ideals with the club's only other member, Yukino Yukinoshita. Unable to reach a common ground, Shizuka proposes that they both contest their ideals by helping people sent to the club, with the winner being able to order the loser around. The following day, Yui Yuigahama enters the club with a request that they help her bake cookies for a "certain person". Yukino tries and fails to get Yui to bake correctly, although Hachiman fulfills Yui's request using reverse psychology which effectively helps her realize that people simply appreciate being thought of. The following week, Yui shows up at the clubroom and gives both Hachiman and Yukino baked cookies as thanks for their help.
