Mona is the most popular girl in school and can make any boy swoon, except one: Medaka Kuroiwa. As per usual, she’s engaging in a heated battle with him to make him fall for her. This time, she also has the help of her fangirl Tsubomi. She tried all sorts of aggressive tactics during the school festival, and even shared an umbrella with him on the way to school, all in an effort to make him pay attention to her! But before she knows it, it’s her heart that’s fluttering! What’s more, she now has to contend with a formidable kouhai who’s also gunning for Medaka. The battle for Medaka’s heart is about to get even more heated!

Asahi suffers an injury while Medaka is watching her game! She is understandably depressed by this, but Medaka's kind words touch her heart, prompting her to confess her feelings for him! Tomo later invites Medaka to a concert, successfully securing her first date with him. Mona might be the ultimate queen bee, but she'd better not let her guard down!

Valentine's Day is fast approaching! Asahi is pouring her heart into crafting the perfect present, and Tomo has also been aggressive with her moves. Mona herself is also cooking up a big plan for the day! What presents are they giving Medaka, and how are they going to hand them over?! Prepare for a volume packed with sweetness, literally and figuratively!

Mona is the cutest girl in school, and she knows it. In fact, she's worked hard to make her high school debut succcessful. Buf no matter what she does, she can't seem to catch the eye of stone-cold stoic Medaka Kuroiwa—but she's not about to give up that easy. Medaka, on the other hand, has been raised at a temple and was told to never become close to women. Who will win in this heated battle of wills?

Mona has finally realized that she's in love with Medaka! As she goes on her first date with him, she has a blast doing all kinds of things couples do on a date, such as feeding him, going to the arcade with him, buying matching items with him, and so on! Being in love has also amplified her cuteness. However, her rival Asahi then strikes back with a bold plan!

As Medaka wanders through an unfamiliar part of the city, a band girl named Anri Shinagawa suddenly drops on top of him! The rebellious girl later gives Medaka a few pieces of advice regarding his precepts. Meanwhile, Mona is sent into a huge panic when she sees how close those two seem to be...

Tomo finally reveals to Mona that she's fallen for Medaka! How will Mona react to this, and what will become of their friendship?! It is now winter, and Christmas, the big event for all couples, is fast approaching! The period before Christmas is just as eventful, however, with Mona asking Medaka to go on a Christmas date with her and holding a study session at her house to help him pass his exams! Not to mention that there's now a 3-way war to win his heart!
