The flash forward teaser is wild because I wonder what will lead these two to go horizontal in less than a week. It would not be a puzzle if at least one of them was intensely forward or had experience, but they don't have that kind of chemistry. They both seem like inexperienced high school students and not particularly desperate, so this fast track progress to their first time is oddly (though not unrealistically) quick, and feels like something out of a one-shot or a series about legal adults. Maybe they will keep renewing a 7-day contract multiple times, so the flash forward actually takes place more than a week in the future? Or maybe the flash forward is a misdirection and the girls will abort mission at the last minute?
I do like their dynamic though, and the setup feels distinct. The short time limit is oddly unnerving, even though I know they will most likely become a real couple. It's hard to recall high school yuri series that start with this kind of casual dating of mere classmates, without a blunt transactional excuse (money, blackmail). That new Usui Shio high school yuri is similar but still pretty different because the character motivations are more clear there and there is no time limit.
