Looks like twitter is getting more and more popular nowadays in Korea.
Another Korean Idols started to make twitter.
It's none other than MBLAQ Leader, SeungHo.
It's verified by Epik High's Mithra, so don't forget to follow him ^^

Official announcement from J.Tunes :
Hello It's J.Tunes Camp
There are so many questions about Seungho's twitter right now
It is real Seungho's twitter, not a fake or stolen one, and we haven't decided whether to do official activities yet
Because of twitter, there are so many people who personally called and asked us about it.
It affects our work, so please try not to do it.
Thank you
