Siwon just updated his twitter account recently and looked like he tweeted a behind the scene's of their album photoshoot for their repacked version C Bonamana album.
He tweeted "Choiminator.. hahahaha :D !! " Saying that this is his version of "Terminator" (You guys are familiar with that movie right?)
Does this ring a bell?
To be honest, he look's pretty close~ beware! Choiminator is coming for you!
