I actually created an account just to comment about this doujin.
So I read the raws up till the end and I can say something about the ending.
It's a happy ending (kind of). Moe ends up with Ran after Ran realized that the dorm mother never really loved her, and it was Moe that could make her actually happy. There was also a back story about the basement, which turns out to be some kind of sex-ed class so the students don't get shocked by the real world when they graduated. The means might be rough but in the end everyone is actually happy and Moe became the new dorm mother with Ran being the new school chairman. There is some forced sex done though, but the one being raped doesn't seems to mind about it in the end
I understand this might not be for everyone, but I'm personally happy that Mira is trying new things.
may i have the link to the raws ?
