Guess you'd call this ecchi. And dumb. BUUUUT, I'll probably read the next chapter! Do some Japanese parents really leave their high school kids alone? Seems prevalent in manga.
Dang! What a great series.
I have never purchased manga. Looking at the retail sites it shows "volume 5", for example. How many chapters is that? Do volumes come out weekly/ monthly? I don't know how it works. Apologies to everybody! 😨
