OK, seriously?

This is turning into a damn romance manga. Did the series suddenly get a surge of female fans or something?

I can see how the current plot will develop now. Nakai and Aoki will still feel for eachother, but both will feel guilty because Nakai is hanging out with the other assistant and Aoki is head over heels for Shujin. Shujin will be doubly confused because Aoki is acting weirder than usual and Miyoshi will discover the truth behind everything making things hard for Mashiro and Shujin. Tanto will probably suffer for all this and not even be serialised for long.

I'd seriously stop reading this manga if Mashiro and Shujin end up as Aoki's assistants.
