For a moment I thought the morals rep was in the stall next to them and getting ready for a threesome. Went back and saw those were his shoes. Maybe next time.
Ooh, a sequel! I'm certainly happy to see it.
Great ending though. Haha, I guess that means in her eyes he got an...upgrade? downgrade? But I guess the fact that 'stupid' is in his title now implies that she likes him enough to be a bit of a tsundere to him. Maybe one day once she graduates, this relationship can be pushed even further.
Also, yeah you'd probably get sacked, so preventing her from going after other teachers is one method of preventing a leak, I guess. But hey, you also get the added benefit of having her all to yourself in that case.
I'd love to see more sequels, and maybe we'll even get to see more of the other girl on page 1?
