Hiiragi's Practice Diary

Yoshiyuki Hiiragi is a rather mediocre student and member of his school's swimming club. To top it all off, Hiiragi is completely unlucky when it comes to love and can't land himself a girlfriend. One day, the swimming club captain Yui Kousaka tells Hiiragi that they can "practice" together so Hiiragi will know what to do when he finally gets a girlfriend.
