MONSTA X posted the second music video teaser for the title track "GAMBLER" of its ninth mini-album "One Of A Kind" on its official SNS on the afternoon of the 30th.

The members in the released video are heading to the same place, dressed in luxurious black suits and carrying mysterious invitations. The door opens and the members gather together to face each other and confront each other in a tense manner, raising questions.

In the process, Min-hyuk and Ki-Hyun grabbed each other by the collar, forming an atmosphere where something big was about to explode, and the members' intense eye acting in the close-up is making viewers breathless.

While all the prepared music video teasers have been unveiled and the entire concept of "GAMBLER" has been strongly spoiled, questions are mounting about MONSTA X's comeback just a day away.
