So why is this series tagged as Erotica? When does that whole deal start?
Beats me, chapter 1 was definitely spicy enough for Erotica, then 2 and 3 still had some vibes but toned down (hard to beat the accidental onsen scenario tbf).
This is the most tame chapter but still had a lot of teasing. But it was focused entirely on one teacher this time, so maybe it'll be toned down to introduce them before going wild?
On topic: damn Orizuru sensei just gives off mommy vibes. But only to MC. I guess she likes teasing outside of class? Or maybe they all just let their guard down after getting used to MC.
In general it's kinda funny how attached all four teachers seem to be to their caretaker/high school student, though all in different ways. But I guess that's harem logic, right? We'll probably get some retroactive explanation later on for all this.
