About the apartments.

Alrighty my beautiful lovely crew I want to update you so you don't feel lost. Her is where it starts; 

Jaejoong, Yoochun, and Junsu have moved into the same apartment complex as Yunho and Changmin. The thing is neither parties know about this it just happens to be a coincidence.(Lucky for us right) 

Yunho and Changmin live in the same dorm so to speak on the top level of the complex. At the top level everything is a bit of a blur thus unannounced to them their former members and best friends move right in to a lower level with-out their knowledge. Yunho and Changmin only able to get a glimpse of a moving truck.(It's not like our JYJ divas would move it themselves right.) So Homin just suspects some random person is moving into the complex no big deal fight?

Wrong! This is a big apartment complex only housing the elite, so at first it may be hard to spot one another, but eventually the five former best friends are bound to run into one another wether it be at the pool, restaurant, lobby or etc.

So guys as of right now I think we should be able to start with no problem lets just get our characters personalities established before the big reunion! 

If you don't know where to start, getting to know your new apartment  would be a suggestion from me, or checking out the complex and all of its amenities.
