THANK YOU!!! Finally, it'll be out of my head
All I remember is that the mcs are both teachers. It's a black and white smutty manga. One of them is a city teacher that got transferred to a village school while the other is a teacher of said school. Last thing I remember was like- the city teacher's ex visiting. (I also think that the ex has a thing for the old principal?!? I might be wrong but, help me.
