Calling Heo Mi-mi a "vacant house robber" is a bit much...

I saw a comment like that.
Of course, many top-tier athletes went to the World Championships.
But there are five players ranked higher than Heo Mi-mi, and she beat all of them to take the gold medal.
It is definitely not "vacant house robbing" (winning an empty field).
She was the underdog who ended up devouring the favorites.
