Well, I can't really say about her not being depressing at first, since I haven't touched Days in months. I never said she did go to the clocktower just to press her problems onto Axel and Roxas, but it did seem like she just made the ice cream scenes more sad, which, again, is not what they're supposed to do.
And I'm surprised you agree on some points xD;
I'm pretty darn sure you don't agree with this. I don't think any person who hates Kairi and loves Xion does.
