after watcing ep7, it's clear (at least me)

Spoiler for ep7:

That at the end Hiromi will be the one. I mean having Shin hook up with Noe with 7 ep left just leaves room to have them and Jun with Hiromi break apart. Also with Ai and the Kiss it's pretty much desperation at this point. Noe and Ai have come out, it only leaves Hiromi for the end.
