Which kpop dance is easiest to learn?

Kpop dances are by no means easy and it is very difficult to learn them if you don't have a background of dance because some of the moves are very advanced. That's why idols train for so long, they've trained for years to dance like that. So with that said, don't get too frustrated when you can't really nail them. But hey, go for it. I try to learn them too. The more simple ones are shinee's hello and snsds gee.
