My prediction is they succeed in the plan to take the town from Guwon and the hounds (or partially succeed maybe), but they don't kill Guwon. Jinwoo (maybe in secret) has him locked up and tries to re-educate him to value human life, but Guwon continues to insist that everyone but Jinwoo are dogs to him. Jinwoo eventually gets fed up and starts getting violent, maybe even torturing Guwon. This makes Guwon love him even more and uses it as evidence that they really are the same. I don't know what would happen after that, but part of me thinks it can't really end unless they both die.
"younger brother" can be a term of endearment in Korean, I don't think the pink haired idol is his actual brother
Did you mean the black haired idol with the same red eyes as Garam? Cause the pink haired one is T-Ren whom Garam mistook as the person Jaechan is having feelings for. And yeah you got a point, but the guy was also saying that their 'eldest hyung' told him about Garam's problem which referred to Garam's actual brother that we've seen before
