I didn't know who this guy was at all but I had to agree when I saw his twitter pic. He really was hot. Like bad boy hot.
And then, after wondering for so long, I was so shocked to find out it was Lee Sungmin's younger brother. SUNGjin. SUNGmin. And they both have the same lips and slightly poofy but cute cheeks.
Lee brothers are so handsome. XD Sungmin has this nice guy look and Sungjin looks all bad ass.
He's an 89line! :D Thank you to Undead29 for commenting me this. :D
His birthday is October 23, 1989 :) - Thanks to Danica for this.
