Isn't America colder?? heheushshauahshhhshshsshhauuwhshshxnfkdhebdkcgsns

I think some Southern and Western states like Texas, Arizona, Florida, California, Alabama etc are hotter than South Korea. I have a few friends and relatives living in USA. My dad's elder brother's wife and my cousins are American citizens and there are a few friends living in South Korea but I've never been to either countries, so I can't really confirm.

The southern part is warmer

Depends on where in America he is going.
