i was exited to see what would happen with Hana (as the main character) and Crash. I really wasn't happy when Yui suddenly came. I don't like her really much. (she kinda annoys me. don't know why) yeah. The change was TOO sudden and too much in my opinion. So I don't think that I'll read the rest.... It's sad, cause I really enjoyed it.. ╥﹏╥ ╥﹏╥
As mentioned previously there isn't a 5th chapter. BUT. At myreadingmanga.info chapter 4 got 3 own "chapters" which includes the end :3
Yeah, it has it's own "chapters" but it's really just the 4th volume split up into 3 pieces. In the postscript of the 4th volume, the author mentions about wanting to make a 5th volume cause they kept straying from what they originally wanted to make. So.. there's not really an end yet.
