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!

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!
