To be honest, I really disliked this update too. The Molly scene was... disgusting and I felt Tsuneyo broke character and outside of those scenes, I did not feel that a lot of progress was made. It awfully felt like padding.
BUT given the track record, I do have faith that
Selebus is going somewhere with this and it is his story to tell. As much as I hate the "But, but Denpa!! Lol" fig leaf that is constantly being brought up at a moment like this, it should be clear to anyone that this is not a porny fan service story like so many others here either.
In the end this update is similar to the dreadful predatory Miku scene, but at least there's some growth this time from Sensei, which counts for something - at least for me.
