Sex =/= love
Sexual feelings =/= love
There was very little love here on Atsushi's part and Yuusuke's love got lost in the absolute mess of his life.
I liked the ending. The final development of Yuusuke was particularly good. Atsushi, seeing as he was poorly developed, only had basketball as a means to develop further. Even with those constraints, Sensei could have done a lot better with his ending.
The manga itself would have likely been better if it was half this length. It was a trial to read and I was surprised looking at the chapters after to see how short it actually was. You can skip this one without missing anything special. On a personal basis I consider it worth one read not two.
