After a bit of discussion in the Mangafox Girl Friends Fan Club, I stand corrected by Nyamotaku. The said date: JUNE 12 was not for the Chapter 32 release but the Volume 4 release.
I then went to Amazon Japan's website to clarify about the Volume 4 thing. What came out was true. The said volume will be released on June 11-12.
I'm sorry for the sudden error. You must know that I'm not Japanese and I don't know the language (as much I wanted to.) I'll try to be more accurate on my research and sources next time. Sorry for the inconvience. >__>
With this, gomenasai.
Ok so I heard that GF will be released May 22. So May 22 it is. ^_^
