Yui loses herself in a school role playing game with heavy yuri themes. All the other characters seem to be present except Takaya, even the giant octopus. She is just getting to the "good part" when Takaya interrupts her. Only then does Yui realize that she was not the only one playing a role.
Takaya has been spending less time at home lately, and has no time for Yui. Yui believes that he is busy with work, but when she Sakuya reports that she saw Takaya walking down the street with a strange woman, she assumes the worst. Yui and the other girls decide to find Takaya and follow him. When they find him and hear the strange woman with him suggest that they go to her place Yui collapses from shock.
Yui lies in a coma. The store manager cannot find anything wrong with her, yet she continues to sleep. Takaya keeps vigil at her bedside, sewing new clothes for her to pass the time. Yui awakes, but pretends to still be asleep, afraid that Takaya will leave her if she gets up. The strange women who precipitated the crisis shows up (later revealed to be the store manager in casual clothes and with her hair down) and only when Takaya gets up to go to her does Yui rouse, grabbing his sleeve once again.
