Yes, chapter 5 is up. Since I don't have a clue about girls, this chapter is based on fansubbed anime, really cheap novels by an author who has been in and out of psych ward, and wishful thinking. I should probably not even try to write the "girls home alone party" chapter which the voices in my head are brewing now.
(Except those voices in my head that are speaking softly in Japanese, using words I don't understand. But it definitely sounds Japanese.)
On the bright side, literally, the pain in my side seems to be entirely faded away now. I like that.
