Thanks for scanlating this. I reread everything from chapter 1 and it seems we have come full circle!
Aizawa <- Wataru <- Ayano <- Jiro (siscon) <- Nishimura (Seiyuu wannabe) <- Murakami-sensei <- Aizawa (probably)
I'm very disappointed that this is an "if" story. I would like to see him struggle a bit more.
And maybe some other characters get genderswapped as well because the curse move around or something.
