I cant relate to rich people. I really can't. Sorry but me and you are different, you were born in a rich family and I was not.
There is not one idol I relate to. When kpop fans say "Oh he/she is so relatable" it really doesn't make sense to me because said idol lives in a expensive dorm, gets paid thousands, can buy designer clothes and purses, and sells anything they release. What is relatable about them?
This doesn't include if you relate to them in a mental health way, because that's a different topic. But overall I do not see any relatable idol, especially from a big company.
