Chen had previously expressed on SBS Love FM's 'Kim Chang Ryul's Old School' that the artist he would love to collaborate with is 10cm, and 10cm followed up with an Instagram post, saying he was shocked and would gladly work with the EXO star. 

The above teaser video captures the moment 10cm heard the news in his car. 10cm then calls up his manager to brag, but his manager responds, "Why would EXO collaborate with you? I'm hanging up now."

Stay tuned for updates!
