IDK what this is but I just found out that Yuto of PENTAGON and his friend Shogo of the JPop-group INI are going to release an MV together or something (?)

I randomly found this on Reddit, tried to research more and than found Twitter-account about that

IDK what this is and what they are going to do, but uh, I didn't knew that these two dudes would do something together

Sure I know they are friends since Shogo is a former CUBE trainee and acording to Shogo he was allways asked by Yuto if they would hang around as soon when Yuto figured that Shogo was also Japanese, but I didn't thought they would do stuff together like that (Man I would like to know what this is cause on Reddit it gave me vibes of an upcoming MV and IDK if thats even one or not)
