Well, there is one story that almost went for the teacher x student, but it became a student x student in the end. It's by the same author, Hirunaka No Ryuusei.
You spoiled it
It doesn't matter if I spoil it, for the first time readers the comments spoil it from the shippers xD
lol i read it, for the majority it seems like she will end up with sensei.. so in the end same sort of issue
regardless i mostly read yaoi and there is a trove of issues that could be brought up there hahaha (〜￣△￣)〜
I just hate that this mangaka writes about High school student x Adult
But her artwork and the way she develops the story is always so great （；＿；）
