If you really read the manga to the point where the is going you opinion from her wiil invert to opposite....
And you all dont know a thing about of her feelings/pain/sorrow why she threaded him bad...
[color=red][edit by mod, WARNING: Possible spoiler][/color]
The reason was she liked the other guy who died in accident and she didn't want to feel the same pain about the person she loves, so she tried ignore him, tread yamato bad to him forgets about her, but yamato didn't give up :x
Slowly Suzuka bit a bit was showing her true colors being the opposite of what it was seen in the beginning.
This evolution is the best part of this Manga and when this moment arrived the Manga improved still more.
I loved this Manga since the beginning, for the art, the characters, the realism (yes because in many Mangas the characters are easy to conquer or they fix themselves more in the fanservice etc).
So don't say shit without having read everything until where it goes >_<
And i am reading many ecchi comedy romance drama like Pastel, Mx0, Gacha Gacha, Air gear, etc.
Therefore when you are to read something you need to see all the factors and the reason because such character reacts like that…
