A lot of the action in the final comes down to Dortmund avoiding dumb mistakes and allowing Real Madrid to score a quick goal. I think that would very quickly end the tension of the game. It is not that Dortmund couldn't come back, but Real Madrid is brutal when they have the lead. Vinicius Junior and Rodrygo love that game when they can wait for these moments to use their pace and their dribblings and have a lot of space. Then I think Dortmund might not have enough quality to strike back, but if they can keep the game even for a long time and here and there take the initiative, I am convinced that it will be a game much closer than all the "Real Madrid is the favorite" screaming fanboys believe at the moment.
I hope it is not like 0-3 at halftime. It would be boring.
There is a gap between the two teams entering this final round, so it is natural that Real Madrid is highly superior compared to the opposing team. as you said, Madrid's front line players will try to disrupt and pierce the defense of Edin Terzic's squad in the final round. Madrid can do this from various lines, plus the midfielders are involved in helping the front line players to penetrate the Borussia Dortmund defense. It doesn't rule out the possibility that the scenario you say in this post matches what you said. Unfortunately, what we are discussing is still based on assumptions that have not actually happened. We know that these two teams have quite a clear gap, especially since Dortmund's performance is sometimes unstable, even in the Bundesliga, Dortmund is currently ranked 5th in the standings. So we can conclude, it seems that almost most of the bettors, or football fans, will definitely favor Madrid as champions of the Champions League this season. The gap is also visible based on the betting market, Madrid's odds are quite low compared to Dortmund.
Honestly, it cannot be denied that I also have the assumption that Madrid will win this battle. but I have to say too, this match hasn't even been held yet. Even though Madrid are far more favourites, the final result is uncertain. in fact, it is possible that there will be surprises. after all, everything involves possibilities. One thing is certain, to find out the champion in this competition. Nothing but wait for the match to be held, we will know the final result for sure.
