Yahari Ore no Seishun Love Comedy wa Machigatteiru.

Synopsis

Pragmatic loner Hachiman Hikigaya writes an essay describing his view on the lives of contemporary teenagers which displeases his language teacher, Shizuka Hiratsuka. As punishment, she forces Hachiman to join the Soubu High School Service Club and requests that its sole member, Yukino Yukinoshita, try to remedy his broken social skills. This immediately results in a clash between both students and Shizuka proposes that they contest their ideals by helping people sent to the club. The next day, Hachiman learns that Yukino was paradoxically made an outcast because of her beauty and relates to her differential way of thinking. Afterwards, Yui Yuigahama requests that the Service Club help her bake cookies for a friend and Yukino fails teaching her the basics of cooking. Hachiman tries an alternative approach and uses psychology to get Yui to realize that the sheer act of doing something for another person means more than how the act turns out. The next week, Yukino and Hachiman discuss Yui's request with respect to the ultimate goal of personal improvement, versus the rewards of working toward said improvement despite risking failure in doing so. Afterwards, Yui shows up at the club and thanks both Hachiman and Yukino with homemade cookies she made herself. (Source: Wikipedia)
