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.
words cannot describe enough how invested I am in how good his character development would be. usually by character development it's always from being an abusive, nonchalant, or and narcissist to the sweetest and most caring person. but this time, it's really just about fixing flaws that the person may find normal but others find annoying and gives them the ick. Leo isn't necessarily one that needs a big development in his attitude, it's normal for famous athletes and stuff to have a big ego because of all the things they've done and gone through to be in that position, but sometimes it gets too much that he doesn't realize he's abusing the people around him too. in short, he's spoiled. so I do hope that the author makes it realistic and not turn stereotypical bcoz it would make a lot more sense that way.
