Even though he takes responsibility(ish?) I still think he should get SUPER-murdered by Hoshi-kun & make it a really vicious scene that they could slip into the story that he secretly had some alpha blood in him or something & he could be super possessive of Tomo....(that's my version of a happy ending---the mega-asshole-sensei gets the crap beaten outta him by Tomo's first love/best friend & they start dating & everything is awesome in the world etc.)
I wish they got their own series together.....*sigh*...I would buy every copy & read em like a billion times. Seriously. Cute. (=・ω・=)
I feel like the author was drunk when they did this.
