No, I think he was holding back that monster bastard's duke so that he doesn't meedle in.
Or more like because he (Giwool, that bastard's duke) tried to hurt him with those chains.
But they didn’t let grand dukes in. Why other guy’s duke was there and how did we see ours even though he wasn’t there? An illusion, an impact or a protecting charm activate on mc or smthing? We know nothing. I said “blind spot” bcs webtoon has a very poor side about so many thing.
I think the dukes were in the audience and, even thought they didn' let them in, that Giwool tried to harm mc. Mc was protected by Jaeyong, who is allowed to be there because he is a king, while ml took care of the other duke. But yes, I agree it wasn't clear enough, I was a bit confused at first.
Grand Duke… how? I thought that panel was wrong first but i think its about story telling. Why this webtoon has so many blind spot?!! Need novel rn :((
