Ochikobore Alpha to Elite Omega
The rape by the creepy stalker was unnecessary to the plot. At max it should’ve ended at just a SA attempt, didn’t think it’s go so far as having the uke be raped and his identity as an omega teacher exposed. Didn’t add anything to the plot. Tsukioka is an excellent teacher at a prestigious school. His only weakness is the fact that he's an omega, but he's managed to deceive those around him so he can live his life as an alpha - until one day he goes into heat at school! What's more, the situation is photographed by Shiizaki, a student who is feared to be the devil of the school. Thus begins the turbulent school activities of a problem child and his well-behaved teacher!
