There’s been rumors saying that Choi Junyoung will be joining Boyfriend next year!
It seems like he has an amazing voice and can understand English very well since this tweets are all in English! Also, he was born in 1993 so he will be turning 18 this year ^^

It said on his Facebook Page that he will be debuting as a solo artist first in January 2012, then will debut later on with Boyfriend in July 2012. He will be introduce by StarShip on this up-coming December. He also said that his solo debut in January had already been confirmed by Starship Entertainment, however let’s wait and see the official statement in December!

I got all of these information from his Twitter and Facebook Page which he said that himself, his close friends and one of the label mate runs the page. So im guessing that these resources are reliable?
