Honestly one of the worst omegaverse stories I have read in a while. The omega clearly does not know the meaning of communication and just one-sidedly breaks the alpha's heart (multiple times) by running away from him and his problems. I'm not entirely sure what message the author was trying to convey here because the actions of the omega are highly illogical and improbable, he literally had no reason to do most of the hurtful things he did in this story.
Honestly, the only likeable character is the alpha who somehow still loves this highly irrational omega and is the only reason they get a HEA. The relationship is a bit toxic in its onesided emotional reality. With the Alpha being the one holding their relationship together.
