i agree it didn't really go anywhere, but it had a pretty good cliffhanger to it. Kaname better fess up and tell her past in the next chapter tho, or i'm gonna be mad.
I hate how Kaname has kinda backed her into a corner. He was really nice up until now, but now he's like bribing/threatening her: be my girlfriend or i won't tell u about your past. I still think she's gonna end up with Zero in the end tho, but maybe that's just wishful thinking ^^
