Who's who and what's the problem?? So what if the outsiders aren't humans what's it that has to do with the forest? Σ(っ°Д °;)っ
Too much to function when I'm dying from headache

People inside the ark thought outsiders are descendants of humans with some animal mixed in. The ark has a society of scare resources, and the forest that the outsiders have lived in has resources. It seems that there's a "alliance" between the very high ups in both society to keep the current peace for information(outsiders get technology as seen in the school, and insiders probably get forest resources to research the safety for human use). Also I believe that mot revealing that outsiders don't contain any human DNA is a way for the insiders to feel as if they have the highest iq still and are superior beings.

So mc was ml's only person whom he was close to after his mom's death and after mc for some reason told him to piss off ml went to live with his father heart broken (so basically mc in wrong here) and now for some reason too mc started to think " oh actually I want him back" and after approaching ml who is butt hurt by him ml tells mc to piss off but cuz he still have lingering feelings he accepts his proposal.. Right?
Now why tf is ml in wrong here it's all MC's fault actually with his unreasonable actions. (/TДT)/
