Wow, yeah. Senpai needs a punch or three. Way too predatory and entitled for my taste.
Exactly! And I realize that she's their Senpai and they are supposed to be respectful, but both of them need to tell her to back off! (Especially Fu-Chan, since it looks like she's still trying to get her to go out on dates alone with her at the end...)
Frankly, if it wasn't presented so lightheartedly, I would be concerned about Fu-chan and Non-chan's relationship. (Like if this was in a serious story and not something that is essentially a gag comic.)
