He really is not. As someone who read the novel thrice now, I still feel uncomfortable whenever I read Chase's side. As if believing you fucked a dog for years is not enough reason, he's also believed since childhood that he's not normal for not behaving the same way as dominant alphas/omegas do (they go quite emotional numb after manifesting, chase does not).
Moreover, the only person he can be vulnerable with is about to leave him too. He had been unstable for years, and feels like he's constantly losing everything. In the novel, he always expressed his fear of becoming as apathetic as normal dominants, but I think it really just wasn't conveyed properly in the manhwa.

Also why is there so many Chase defenders in here like pack it up, y'all as dramatic as him.
