Did You Know? {Kpop Edition}

Another one of my Did You Know books! This one will have facts about Kpop, because I like Kpop more than American pop. If you are a Korean pop fan, then you may read this. If not, read my other Did You Know books (original or Minecraft). I don't know if I'll make another Did You Know, but I think I will make a sequel to the original one. Like all my other Did You Knows, I do not own any facts, and if you have a fact to give me, comment it and I'll post it and dedicate it to you.
Anyways, open this book and be amazed by all your bias and other Korean stuff!

[PS. Try to name as many bands as you can in the cover.]
