Kotonoha told Shinya and Ayame, they need to go on a date and while Shinya agreed, he requested that Kotonoha to define a "date". Kotonoha then started thinking about a past moment with her teacher Takahashi and how another student couldn't come, so she ended being alone with him and was excited it was a date. As Kotonoha was about to start explaining, Kosuke joined the conversation. In his version of a date, he would bring Aika to an amusement park and the haunted house, where she would hold tight to him, but Kotonoha realized he was talking about a game. Ena then joined, saying that otaku like Kosuke, can't possible know. As she started explaining her version, Kosuke realized it was also a game and Shinya was shocked that he and Ayame was both males in that love story.
As they made a list of what a date is, Shinya was excited to conduct it and was ready to do that experiment, but Kotonoha stopped him, telling him, he first needs to ask Ayame out on a date. He didn't really find a reason for that, as she already agreed, but seemingly Ayame wanted to, so while blushing he asked her out. Getting quite happy about it, Ayame told him they had already decided to do it. Ayame then brought out the amusement park map, so that they can make the most efficient and the greatest date route. As they marked all the location they are going to visit, they asked Kotonoha if she can optimize the path as this was what she was best at and loved doing. Kotonoha then explained and showed it the complete route and how to optimize it. Shinya got excited that even if you use this method, it still can't be said to be the best and started doing his research. Kotonoha wondered if they did really need to optimize it, but both Ayame and Shinya told her that this way they can go on more dates and then started competing with each other, to see who can make the shortest route.
