Rain and J.Y. Park are all but ready to exchange some blows, as they prepare for their anticipated collaboration unit debut!

In the first MV teaser for Rain x J.Y. Park's upcoming duet single "Switch To Me", the two stars seem to be having a fancy night out at a bar, dressed sharply. Sipping drinks, the two stars begin with compliments toward one another which quickly escalate into offhanded insults. 

Curious for more? Rain x J.Y. Park's collaboration single "Switch To Me" will be out this December 31 at 6 PM KST!
