I don't think I've ever seen this trope before in manga or anime. But I'm here for this Freaky Friday situation.

I was really sure that I would hate this initially, so certain that I almost put this down because I found Azusa just so annoying.

But I am glad that I didn't put it aside because once we get into the plot, Azusa's obsessiveness tones down and becomes a genuinely good piece of humor that I didn't find myself cracking a smile to.

I will definitely be continuing with this manga.
