I second this, I am bit disappointed that a new girl per chapter didn't last a bit more, but I am sure it will still be a good time, just hope it will still last a while a more.
Totally understandable-- in fact I would've loved to see a couple chapters with new girls, but to have them all recurring characters would've been a bit of a headache, seeing how most, if not all of them are Mai's co-worker/friends.
But I'm also glad it didn't stay past its welcome....'else it would've ended up like a Yurika, where I have absolutely no idea where that plot went...
That being said, I went absolutely feral over this chapter. So much anticipation...!!
