Maybe I'm biased, because I've personally been in a Mitsuki-like situation for around 18 months too, with a gorgeous dark-haired big-eyed girl (sonds familiar, eh?
... without getting the true Mitsuki ending (only the "good ending", so to say).
In episode 1, Takayuki's interest in Mitsuki was obvious to the audience, but not to her. If she had pursued him by then, she certainly would have won over Haruka, but she did not - and not because she's the timid type, but because she obviously didn't want to betray Haruka, her friend.
However, she wasn't quite strong enough to suppress her own feelings, which eventually also led to the accident, filling her with guilt up to the rim. Partly her own feelings to Takayuki, partly her immense feeling of guilt and responsibility make her take care for him for over a year. Just trust me on this, to keep this up with a person as destitute as Takayuki for a year without slipping is a huge feat.
She didn't plan to "take advantage" of anyone. In ep5 she's first seen suffering at Haruka's bed on her own. Also, leading up to her making her move on Takayuki - right after he was told by Haruka's parents not to return - she tried to get him to ACCEPT this message and move on. She said that Haruka was never going to wake up, and that things are going to stay like this, so Takayuki should DEAL with realities (ep5). Maybe a bit of wishful thinking, but not overly so. And THIS was when SHE cracked herself and confessed. She was falling apart too, folks. AND she saw Takayuki snap for over a year, and getting much worse (Takayuki taking Haruka to the exhibition, anyone?)
All those Mitsuki-haters should have a quiet minute and wonder:
1) Where would Takayuki have been without Mitsuki
2) Would have Haruka wanted in this kind of state? Would she have wanted Takayuki to go through hell like this?
In a nutshell, Mitsuki has several flaws and edges, but she's been the glue holding this group of people together, through all episodes. So don't condemn her too harshly
... she's not a bad person at all. Just someone who made a poor call out of good reasons in the beginning: Suppressing her own feelings for Takayuki for the sake of her friend. And this eventually became too much for her to deal with. Very human.
to everything except the last, confessing your love is one thing but jumping a highly vulnerable guy is seriously wrong, If it were switched and the lead was a girl and her BF was in a coma, and a guy confessing his love then jumping the girl, everybody would cry rape or call him the biggest ass on earth.
