MONSTA X‘s Jooheon and Kihyun (also referred to as 2Chain), have come together to deliver a special gift for their fans.

As a celebration for 600 days with Monbebe, their fans, they collaborated for a cover of Crush‘s “You & I,” showing sides of themselves never before seen.

During the passionate cover, we get to hear Jooheon sing and Kihyun do a short rap verse. It was also revealed that member I.M participated in the track as well!

MONSTA X has also recently celebrated their 2nd year since their debut on May 14. The group is also embarking on their first world tour, with stops in the U.S.
