While looking for the cause of Mai's Adolescence Syndrome, Sakuta ends up scheduling a date with Mai. On the day they promised, Sakuta tries to help out a lost little girl on his way towards Fujisawa Station. But, he is misunderstood to be a perverted maniac by another girl, and because of that, he ends up arriving late to his appointed time to meet Mai. He somehow gains Mai's forgiveness and they proceed with their date, but Mai changes their destination and takes Sakuta to Shichirigahama Beach.
There, he explains his own experience with Shoko Makinohara, an upper-class senpai who has helped Sakuta and his sister Kaede when the latter had a serious impact from Puberty Syndrome. After, both Sakuta and Mai realize that Mai's invisibility has gone worse, with even her mother forgetting who Mai is. With this event in mind, Sakuta and Mai ask numerous people in Fujisawa and Ogaki for the identity of Mai Sakurajima. With no one able to recollect and information about Mai, Sakuta and Mai sleep in a hotel together.
