It’s…Natsu-Comic Episode 6

Yūto and Haruka attend the summer Comiket convention together, but since it is the first time for both of them, they underestimate the massive scale and hoards of people who attend. Mika, Hazuki, and Nanami tag along in disguise and help Haruka obtain a dōjinshi she wanted, and to get her out of trouble when people started taking pictures of her. Yūto and Haruka grow closer throughout the day, but after he leaves her at her house, Yūto is asked if he and Haruka were followed by anyone at the convention, but he says he did not see anyone like that. That night, a frantic Haruka unexpectedly shows up at Yūto's house.
