Are Koreans who like Ronaldo stupid??

The group of people I understand the least
is Koreans who like Ronaldo.
In 2019,
he played hard in China, but when he came to our country, his fan service was absolute trash,
and the next day, he was even seen on a treadmill.
Despite this, I think Koreans who suck up to Ronaldo are abnormal,
but there are surprisingly many of them. Especially those 10-20-year-old guys; they need some discipline.
