my best guess about Yusa's powers is it's similar to a succubus'. he can absorb energy off those (humans) who i assume once interacted with a demon that's why they're being leeched off by this dark aura. it could be why Yusa doesn't have much food in his fridge, because he can strive off of absorbing this aura.
I really love Euihyun. Like a kitten exposed in a world of no peace and had no choice but to strive alone for himself, of course he's going to grow up overly cautious and making violence his form of self defense. For someone like him who lived in an environment like that, trust issues is already a given. It gives me a sort of relief to see how much he's slowly opening himself up to Taeju. I don't think people understand enough how well portrayed or written his character is. The look he gave Taeju before bursting into tears is similar to tearing up despite being angry. Imagine having a lump in your throat from having to hold your cry in, but it becomes so unbearable that you can't help but to finally burst it all out. I don't normally like this debtor plot, but I really genuinely love Euihyun as the character he is.
it's giving "somebody dares to cover my beta with alpha pheromones and i'm mad about it so i'm gonna do non-consensual things to my beta for being clueless"
no wait you're right on the money on that one wtf
