Im interested in the younger brother's angle because its clear that he's transmigrator/reincarnator similar to the MC (And that they may have known longer than the MC). Especially because everyone thus far in the MC's memories have had a lookalike in the novel, like its obvious that the Sunbae in the MC's memories is the ML, and even his bestfriend in the novel looks and acts like his bestfriend in his memories (short hair, energetic personality, etc).
So, theres a chance that the younger brother could actually be an reincarnation of his sister? It makes sense especially because she was the one who introduced him to the bl novel, and the fact that the younger brother knew the title and knew the role the MC played in it which contributed to his fear and hatred towards the ML who led his brother to suicide in the original. And maybe thats the brother/sister is heavily protective over the MC's character because they're projecting the memories of their actual brother onto him, unknowing that that's their actual brother.
If this theory is true it'd just mean that the MC actually cussed out the person he's longing for the most, so uh. ( ̄∇ ̄")
Spoiler alert
So yes mc's brother now is his sister, the hyung is also the same hyung from his real life. Actually mc is in a novel that was made by both his brother n one of mc's friend that still doesn't made his appearance yet. They use mc's name as a joke n actually both of them realised they're in a novel. But the worst thing is they make fun of mc behind his while back laughing at him for having a mental breakdown when mc 1st realised he's in a novel. Yes, the brother and that friend knows EVERYTHING but stay quiet bcs it's funny. In a later chapter mc will discover all of this n will have a huge fight with his brother to the point that he got a really bad depression more than he is now. It's so worse mc will stop functioning to the point he needs someone to even feed him. The hyung will always stayed by his side at that point bcs he got his memories back. So FUCK THAT BROTHER N FRIEND
Its not as simple as saying "you can't save anyone if you're overworked!" Or tired, and whatnot as literally a second he's not in action equates to the deaths of hundreds of people, he otherwise could've saved (not to mention in his experience, complancency or even a minute of time to spend with his family literally resulted in a genocide). He literally cannot afford to rest, despite how stupid as it seems to us. So, what he's hearing from the MC is not to simply just "rest and leave it to the others" but rather "let them all die".
And even though there's a good amount of hunters who are competent or at least the same rank like Esther, no one can measure up to his work ethic and his contributions to the lives saved (not to mention from his viewpoint if he can do the job of 50 hunters, why risk the lives of 50 other people). People aren't statistics, and he knows this. He's definitely been conditioned by the pressures that come with being the so-called "number 1".
Hopefully, he'll stop blaming himself and start to trust others once he sees how "strong" the MC is, then the burden of being the strongest will he taken off his shoulders.
