What does this mean? "넌 어떻게 빅뱅이 돌아온 다는 것을 한국인인 나보다 빨리 아냐"
Hey guys I'm still learning Korean and I need help translating this. Thanks! ^_^

I know
넌 = You
어떻게 = How
빅뱅 = Big Bang
이 = Subject marking particle
돌아온 = come back
"다는 것을 한국인인 나보다 빨리 아냐"
And that one is like "All Korean people more than me quickly".
And I know "아냐" means no.

If someone can help me with this, I'd really appreciate it.
Thanks! ^_^

Answer

넌 = you
어떻게 = how
빅뱅이 = Big Bang (subject)
돌아온 다는 것을 = the fact that (Big Bang) comes back (object)
한국인인 나보다 = than I who is a Korean 
빨리 아냐. = know earlier

How do you know the fact that Big Bang comes back earlier than I who is a Korean?

Answer

OMG you and your friend both are soooo cute.
Are you guys the fans of bigbang? :D
This is not an answer of you question though,
I just wanted to say this.

I guess your Korean is getting better and better from now on.
I know a lot of people who are someone's fan incredibly learn languages fastly.
