The history ain't that good, yes ok gorgeous woman vs beta dude, but jeez almost 80 chapter and they did not even kiss, to me this is the embodiment of a cheap ecchi made to sell as much chapters as possible, they try to force a haremish route without actually a harem, the teacher is a asshole by cheating her husband but not letting the MC stay with other girls. To be honest I am not against virgin/inexperienced in sex MC, but dude this is simply not progressing to anywhere I can take chapter 20 and compare with chapter 60 and they are basically in the same level of romantic development.
