Re: Seiko is going to kidnap Kozue to be her little sister.
Kozue blinked, and opened her mouth a bit to respond—well, she hadn't heard that rumor! "So, you… with girls?" Another blink.
"Soooo… What was it like, anyway? With just a girl?" Oh, god, she should not be asking curious questions! If she seemed like, like— "I mean. Or with a guy, too? Because someone, um, asked if I would do that." She gave a nervous laugh. "And I was drunk but I'm pretty sure I agreed to it some day in the future. If I didn't do it and just don't remember."
Which she was pretty sure hadn't happened, because Maeko didn't drink and would have remembered and things would have been way more awkward in Paradise. And she had woken up after her birthday party disappointingly clothed and disappointingly in her own bed. So, all signs pointed to not.
