NCT Shotaro covers EXO Growl + NCT new member?

The suspicion is that he might be a member from a new unit but no one seems to have any good info here..

I read on reddit that he could be a back up dancer

some people are saying he looks like Renjun but i feel like it's not him. If it's him then i really fail my akgae test

I heard that it might be Renjun but then I don't see why he would hide himself in the first place.

I don’t think the side profile looks like Renjun at all. But I admit I’m not as experienced with the Dreamies - a better Dreamzen than I might know better by dance style etc..hey NEO , your thoughts here?

I really tried to see but i don't notice any birthmark on his hand too

He's tiny
