Episode 3 is adapted from chapters 6-7 of Volume 1
During gym class, Hachiman practices tennis against a wall by himself because he doesn't have a gym partner. At lunch, Hachiman eats alone at his favorite spot because of the nice sea breezes that blow in from the shore. He is interrupted by Yui. While they chat, they are both interrupted by Saika Totsuka and Hachiman is fooled by his androgynous appearance.
The following day, Hachiman pairs up with Saika in gym class, who asks Hachiman to join the Tennis Club in order to raise their strength. Unsure of what to do, Hachiman asks Yukino for advice. Just then, Yui shows up with Saika who requests that the club help him with tennis practice. Over the next few days the group is subjected to Yukino's tennis drills with no noticeable improvement.
One day during practice Yumiko and her clique show up and demand to use the tennis court. Hayato Hayama and Yumiko make a wager with Hachiman and Yui to have a doubles tennis match with the winner being able to use the court and help Saika practice. As Yumiko and Hayato steadily gain the upper hand, Yui sprains her ankle but gets Yukino as her replacement. After a bit of pregame banter with Yumiko, Yukino steadily dominates the game until her stamina runs out, and entrusts the game to Hachiman. Hachiman uses his knowledge of the sea breeze's speed and direction and is able to win the match with a "magic" pop fly.
Even though they win, everyone ignores the Service Club's victory since Hayato protects Yumiko from injuring herself after Hachiman's final serve. After the match, Yukino leaves with Yui, while Saika thanks Hachiman, who remarks that the "god of romantic comedies" is a moron for the end pairings, which seem homosexual. As Hachiman returns to the club room, he walks in on Yui and Yukino changing and is knocked out with a tennis racquet before complementing the "god" on his sense of humor.
