Trama
Yūto, Haruka, Mika and Nanami become increasingly worried about Hazuki's attempt to distance herself from the family and thus decide to follow her on a shopping trip, meeting up with various familiar faces like Yūto's otaku friend Nobunaga, Yūto's sister Ruko and their teacher Yukari. Mika and Nanami eventually becomes distracted in buying lingerie, leaving Yūto and Haruka to the job and almost came to a conclusion that Hazuki was about to get married and quit her job. Before going home, they had a misunderstanding with a bridal shop where they are thought to be customers and were given a chance to take a portrait together with Yūto wearing a tuxedo and Haruka in a wedding dress. That night, Hazuki, much to everyone's relief, explains that she is not quitting, but was just going to a hardware store, which was located above the bridal shop, to fix her chainsaw.
