I suspect the preview that got everyone all excited is really about Yumi dragging Sensei with her to go save Yuki from herself.
In true comical fashion, it’ll be:
- Yumi starting to suspect something
- confronting Yuki but receiving only dubious answers
- deciding to go on a tailing mission to find out more herself
- bumping into Sensei by
fate accident
- making too much noise and her cover is about get blown
- immediately finding cover but
unfortunately ending up in the love hotel by
fate accident
- prying info from Sensei instead
I hope all of these are untrue. My best scenario is Yuki is healthy and Yumi wants sum fuk, or it’s Yumi’s RAS enrollment ceremony.
