Ok, soas you know from my story  "Child's Play" 

I love the idea of Beast and Btob interacting and collaborating 

well

Check out this song with Beast's Yang Yoseob and Son Dongwoon

And BtoB's Lee Changsub and Jung Ilhoon

For the OST of "When a Man Loves" 

BYE BYE LOVE [►]

I get the feels just hearing them together *tears up*
