ML's brother was super shady because why did he tell Yiyeon to make sure he doesn't leave the town? If he actually cared, wouldn't he have done something for his health instead of trying to confine him (kinda)? Also, he hasn't contacted Yiyeon regarding his whereabouts/condition so far, so it doesn't really look like he cares much for ML.
So, here's a lil something that I am speculating. Maybe the brother used ML to take care of people who got in his way? Maybe he did something to alter ML's brain, as in, he used to be a normal dude before big bro decided to do some shit?
I just might read the novel to satiate my curiosity at this point.

Mincheol is a well written character. He has complex thoughts, he does things you'll find people doing irl as a result of mashup of their thoughts, and what he wants out of all this is pretty simple akin to real world people. Your brain has tons of thoughts, you fuck up, and in the end you still want something oh so simple yet selfish.
Other than that, would love to see how his brain works when his shit gets wrecked and he starts regretting everything.
Is Karlyle ever gonna be able to feel secure about himself and his relationship with Ash? He always keeps second guessing and all, and I swear I am gonna lose it if we don't get more side stories with him NOT being like this.
