Is this actually the end of the series as a whole, or the end of this one couple in particular? The "next dream" line in the end made me not sure.
Either way, if this is the actual end, than I'm glad I could go through this journey. My favorite kind of ecchi is exactly the kind this manga has always aimed for, and I can't say I disliked any of the teachers or pairings, although there were ones I liked more than others. I'm definitely satisfied!
Now to look for some other comedic ecchi with absurd hijinks that nails it just like this one :')
