There are only two types of people who are angry about the Asian Games victory

The first type are those angry at the coaching staff and the association, who are praising themselves for getting military exemptions just because they won a tournament like that.
The second type are the Japan-worshippers.
Whenever Korea beats Japan and advances to the finals or semifinals,
they say things like:
"Korea is a first-tier team because of military exemptions, while Japan is just amateur."
"They're acting like that just because they beat Japan's 3rd or 4th tier. If the first-tier teams met, the score would be doubled."
You can see the answer just by looking at that.
They don't say these things when we win against China or Iran, but they uniquely bring up these kinds of excuses whenever we beat Japan.
