Agreed

The Seme wanted out because he truly loves and wants to seriously go out with the Uke. So that jerk geezer wanted to let the Uke knew that he's the one who left him, not the Uke left him. It's reaction of a loser! (︶︿︶)=凸 (Arrkkk~ Never thought that in my life, I would have a chance to use this emoticon)

Totally agree. The seme really liked the uke so he said - Not doing this anymore for the jerk off. I think the sensei has control issues. Exactly what you said. The jerk geezer wanted to let him know that. I'd love to see a development where the geezer realizes he wants the uke back. It'd be a good plot twist and allow the seme to pop the geezer in the puss.
The sensei character is pretty odd. He doesn't really make sense. If he hired the guy to keep him occupied, and it worked, why bring it up at all?
