It's the day before the school festival. Shiina and Yuuto run into an accident while they are working hard to finalize things, and it turns out looking like Yuuto pushed Shiina over onto the floor. Haruka, by mere chance, walks in on them right at that moment. Yuuto runs after Haruka, who had run away red-faced, and tries to explain that what she just saw was just an accident and that there's nothing going on between him and Shiina. However, Haruka just answers, "I know that," and runs away again. Yuuto continues to feel awkward even as the festival begins. However, surprisingly, Haruka comes to school with a smile, like nothing ever happened. Haruka seems excited to be in a cute cosplay costume and to enjoy working at the café, but…

The party has started and Yūto is dragged inside the party hall by Mika. While waiting for Yūto's turn to present his gift, he again bumps into one of the guests and his gift is ridiculed. Yūto becomes insecure and is about to leave the party hall when an old man, who happens to be Haruka's grandfather, helps Yūto regain back his confidence....
