Yeah I know, I find kind of annoying when the seme and uke are the same, but that's their style so what can I do?
Um at the end of chapter 3, the impression I got was that they just moved on with their life. Takashi had left, and had learnt from his experience, now looking for a job that he's able to handle. I guess the brother, since he cried, maybe healed a bit. And just moved on
Does this help? I don't really know how to explain it.. :/

I'm guessing it's like a parallel universe? since the characters' appearances and names are the same..
I liked the stories. (except the last one, that freaked me out lol) It was kinda awkward that the characters are the same in every chapter though lol.
Anyway, can someone explain to me what happened in the end of Chapter 2? It seems like Kouichi healed since he can now complete the origami, but what happened to Takashi and the brother?
