I suppose, the Author didn't really have any idea of how to implement the story for chapter 1-3 and gone to chapter 4.
So, here we are. The story is almost over. What a farce...
I was hoping for more adventure, but I guess it's okay, since the Author crossed the line with Sei-chan, being corrupted by another woman.
I regret to inform you, but this went from 9 to 4/10 for me.
