Even if it is a Ecchi Manga and we should not expect much story but I have to agree with @Pringus that this is just awkward. This series turns more and more into something strange. I like sorts of Ecchi a lot but I should have stopped after the anime.
It's been over a year since there was anything about these characters. These characters were immediately prior to the shota. We've been stuck with the shota for a year. Shota paired off with someone and now is in post-resolution "what if" overtime and I hate it.
