Frankly Mitsuki has a little love emotion problem. I'd like to have seen Takayuki quit his job and go missing :P

She does partly due to her decisions, but I don't think it's her fault.
She tries to be a responsible figure, for example, helping her friend by building Haruka's relationship, then, even though she felt responsible for the tragedy she tries to suppress her emotions and assist one who isn't as capable as she is.  IMO, she handles situations quite well actually.
Of course, she snaps after a while...  I don't think you could call her insane for her actions in the first half of the show.

No, I'd say that was more of a conditional reaction.
I mean seriously.  She's been spending much of her time devoted to helping and caring for her high school crush.  What the hell has Haruka done?  Heck, Haruka wouldn't even be in the picture if it wasn't for Mitsuki.  And why should Mitsuki give a damn over a girl who's probably going to die soon?
