Yahari Ore no Seishun Love Comedy wa Machigatteiru.

Synopsis

Yui interrupts Hachiman while having lunch outside at his favorite spot and excitedly tells him about her growing relationship with Yukino. During the following gym class, Saika Totsuka practices tennis with Hachiman and eventually asks him to join the tennis club. Hachiman then asks Yukino for her opinion on the offer during the next Service Club meeting. However Saika arrives and requests that they help him practice tennis for the next few days. While the group practices one lunch time, Yumiko and her group demand to use the tennis court and ignore the fact that Saika has permission to use it. However Hayato Hayama proposes that they have a doubles match with the winner gaining access to the court. The match then begins with Hachiman & Yui vs. Hayato & Yumiko, until Yui sprains her ankle and switches with Yukino. After a bit of pregame banter with Yumiko, Yukino dominates the match until her stamina runs out and entrusts the game to Hachiman. Hachiman then makes his last two serves by using his knowledge of the sea breezes and hitting the ball in a high arc, which wins the game. Interestingly enough, the spectators end up ignoring the Service Club's victory when Hayato saves Yumiko from injuring herself from the final serve. (Source: Wikipedia)
