It definitely feels better to read the prequel first which is "Hana and the Beastman" because this manga has some references (like the being saved from the tunnel) but they're just tidbits so it's not a necessary read. It is still recommended though. It's the ML's parents' story.

This one got Elon and on another work, we got Trump (the work is "The Investor Who Sees the Future"). There are a lot of non-problematic entrepreneurs that these authors could choose, but nah, they gotta glorify them? like... Seriously??
I still gotta give it some leeway because atleast Elon was drawn ugly here and it has only been 1 chapter.
