If you love comedy and a weird plot with many ecchi Lolicon moments then you'll love this manga.
They have many unique, funny scenes, and the fan service is amazing.
Some great examples... Lots of Loli fanservice. The girls are cute with their quirky personality but they are all lovable.
Also, the teacher gets into many misunderstanding situations which makes it comedy gold. It has many surreal moments but in a cute, funny, and erotic way. But it's always erotic in every chapter.
But I do have to say, the romance is quite sweet.
Edit: The ending was beautiful!
The only thing that can be disappointing is that there is no sex, which would have been a great hentai doujin.
My personal enjoyment is 10. It's fun to read.
The art style is great and it is fitting for the story.
