(First of all, I'm sorry for my bad english)
Maybe not all of you know about pairing, just like newbie in this fandom. Shall I explain about pairing?
Pairing....
I don't know who publish this "special" for the first. But both fans and idol know about that.
Pairing is two member who always together (but sometime not always). Two of them share their love each other, and sometime show it to the fans. Just like hugging.
People usually call it member-ai.
They do something that can make fans scream , called fan service.
I'm sure that you will not understand "why they do that?" or "what is that for?" or "huh, but they are guy!" at the first time. But, you will understand it someday.
But I will tell you now. They are truly a man, Mereka laki - laki tulen, who love girls like the other man.
These are some pairing in Hey!Say!JUMP :D
