only? hwang in yeop had no leading roles, he acted in two tiny web dramas, had 2 supporting roles, and this was his first main role. he was never the lead. he had only 4 projects prior to this casting and you're saying "only". this rookie actor, and he's the definition of rookie, outacted eunwoo in every possible way.
Inyeop is a full-time actor, and all his roles minus one so far have been a variation on the same theme as Seojun. The role wasn't particularly difficult either, and it's entirely debatable who out-acted who.
Meanwhile, Eunwoo - who I thought did very well in True Beauty - juggles being an idol full-time alongside acting. He's been the lead in three dramas so far, and he did indeed get plenty of positive response for Suho from Korean media outlets.
And people here talk about playing in your own league, but they're criticizing Eunwoo's performance in a teen drama like it was meant to be Oscar bait. That's the little league, what's the problem? He was the first one they cast, so clearly they were happy with him and built the rest of the cast around him.
