[Finished chap 1 + a few more pages]
This series revolves around a male teacher making a female teacher cosplay to have sex. Simple concept, plus repititive scenes make this manga a dull one.
A lot of scenes were not explained properly, like why the female teacher keeps cosplaying for him. It doesn't even seem like there was any romance between them.
In contrast, maybe you would like to read Cheers, another series by the same mangaka, and have a theme around cheerleading. The art is a little better as well.
O PS. At the end of every chapter (up to end of vol 1), they would show you
what costume is to be up next. Lol.
