I like these types of zombie stories, they just express how humanity would actually regress too in such a situation, the elites will already existent greedy for power and money will just be amplified in such a situation.
Most of what's happening in this story can be connected to our current situations whether they are civil issues, political issues, humanitarian issues, poverty, the abuse of big pharmacy and big health organizations, and so much more.
I overall I really love this story I hope MC bbg and ML bug guy end up together whichever way they end (till death do us part I hope)
