Jesus christ. Idc what anyone says this is such a good ending. The last chapters were absolute art. Author cut it in 7 chapter and did it SO well. This is why a story doesnt need to introduce so many secondary plots, this was simple to the point and most of all (specially kokonoe or however its spelled) is shown rather than told. We as readers gotta think what happen to each of the girls (psychology wise) and of course sensei breaking down in the last and second to last chapter are weird (age and everything) but wholesome. This ending is way better than OTHER mangas and makes me wonder why.
