Just finished season 1. I had to find the last chapter on other websites. Anyway I pretty enjoyed the story. I didnt read a whole lot of Alpha/Omega story yet. I dont know how Toxic they can be. From what i saw in comment. They can be pretty toxic. Anyway at my opinion this one is not that toxic. Its the story of a guy who all his family been alpha... he was supposed to be alpha... but ended being an Omega. He got traumatized by that... he has a lot of resentment and push that toward the ML. I would say i understand his side since the action of the ML been affecting him. The ML is a total green flag, obsessed golden retriever. But he didnt realize that his action harmed the MC. But he do at some point.
At my opinion, its not a story you can take a side.
