Well, I have to say that sadly I really can relate to Midori in this situation. It's the first time I believe the "can't comunicate" cliché. Sometimes expresing what you really want and feel can put you in a position of vulnerability. It's really hard to deal with the idea of being rejected, specially if we talk about Midori who has low self-steem. On the other hand it's understandable that Haru wants Midori to tell her that she wants both to stay together. Everyone needs to feel loved sometimes and Haru doesn't really have that in anyone right now. Both of them can help each other in this, but, the way I see it, it's up to Midori to speak up.
