Spoiler for speculation:

why does it feel like Hiromi is going to end up sleeping with Jun?

Spoiler:

Because tragic events and sorrow seem to be drawn to her magnetically?

Seriously, I could see a really bad ending for Hiromi. She's in a terrible position in life and doesn't seem to like herself very much. That would be a bit of a left turn for this series, but I don't think it's out of the question. There have surely been some sizable surprises in the first seven eps.
