"Senior! Today is a great ○○ day, you know!" The junior constantly appeals to their beloved senior, and while the senior somehow ends up entertaining them, the two are actually mutually in love and flirt with each other every day.

"Senior! Today is apparently a good day for childbirth! So let's become a married couple and make a baby! Right now!" Shino Shinomiya (四宮 詩), a first-year junior high student, came to bother me again—Mitsuki Kaidou (海藤 深月)—as I was leisurely reading a book in the literary club's clubroom. She's at the top of her class academically and is such a beautiful girl that she won the school's beauty pageant. After I helped her when she was being harassed by delinquents, she started coming to the clubroom every day like this, making appeals for unclear reasons. It seems this time she's planning to make a strange request playing on November's calendar observances. "...First of all, we're not even dating, so we can't make a baby." "Then let's start dating! Come on, first let's submit a marriage certificate!" "The conversation jumped ahead because we suddenly started dating... If we're going to be a married couple, then things like this would be okay, right?" "Eh...M-Mitsuki Senior!?" When I tilted up Shino's chin as she kept coming at me, her face turned bright red and she ran away. Yeah... When she's the one making appeals, she's amazing, but the moment I attack back, she becomes so weak. That's why whenever something is said to me, I counter-attack like this, making Shino flustered and embarrassed—and I get to enjoy this incredibly cute Shino that I love so much. "Senior Mitsuki! Today is apparently a day to say yes! So please say yes to all of my requests... Wait, why did it turn into 'I love you'!?" "Senior Mitsuki! Today is apparently a day for big breasts! So as a special exception, with my ample... why are you coming closer... A-are you really going to touch!?" "Senior Mitsuki! Today is Pocky Day! So let's play the Pocky game!... We... did it... My first time... I gave it away...!?" —This is a story of a somewhat noisy and lovey-dovey November between a high school girl who makes constant appeals to her senior whom she loves dearly, but always gets counter-attacked and turns bright red, and a boy in the prime of adolescence who secretly harbors feelings for her and somehow finds himself enjoying her strange requests.
