My feelings after reading this:
like being slapped--tried to avoid it--but then got smacked square in the face. This story is devil-spicy good, burns the mouth but still leaves you with a savory taste.
I say I sympathize with Chinami more than with Yukako. Relish the day of reckoning huh. I would be equally satisfied if Chapter 4 had been the end but I would also love to see Yukako's move here. Would she try to break free from her sham marriage and try to win Chinami back?
I don't know.
All of the chapters have that [END] tag. From chapter 1 I was a little weirded out by how (what I thought was) a one-shot had ended, but per previous posts, there's 6 chapters plus an extra in all.
One way to find out then. Cheers to the author and the scanlators.
