I guess that when I was new to kpop and kdramas as a teen, I kinda had thoughts like this.
And was also thinking stuff like "I wish I lived in South Korea".
I think that I sometimes watched some videos that were like "South Korea has this cool thing." and then wishing that my country also had that stuff or something.
And based on some stuff, it seemed like a "kpop and kdrama paradise"
I think there might be people too, who think that Japan might be some cool country and "anime paradise".
But well... no country is a paradise.
And imagine having high expectations of a country and then feeling disappointed, when that country is not like how you imagined it.
I have heard that some students from my country had been in Tokyo for a trip and complained about the city being too "village-like". (not sure what they meant by that...)
I don't know if they maybe had some high expectations before going.
