They were dressed in all black with full makeup.

Rumors started arising about Red Velvet‘s Irene and Seulgi possibly preparing to debut as a sub-unit group after a fan spotted them filming!

A fan tweeted, “I came out to play and I saw Irene and Seulgi filming…” This one tweet broke out in rumors that they were filming a music video for a sub-unit as hundreds of fans commented and retweeted it.

놀러왔는데 아이린이랑 슬기봄 촬영중.. — 🍀 (@Blush_xo) April 6, 2020

The original fan clarified that it didn’t seem like they were filming a music video.

What’s with all the response.. Irene and Seulgi.. I briefly saw them but I think they were filming a reality show. It wasn’t a music video location, and it didn’t feel like they were either — @Blush_xo

But the fan explained that both of them were wearing black clothes with full-makeup. Now that she thinks about it, she wonders if it was indeed a music video filming and that she just couldn’t see it very well from the dark.

But they both had full makeup on and black clothes.. Maybe because it was dark.. What if they really were filming for a unit promotionㅜㅋㅋㅋㅋㅋ — @Blush_xo

But then again.. I guess you can be filming a reality show while dressed like that, right..? — @Blush_xo

Are Irene and Seulgi really preparing to debut as a sub-unit group? Imagine spotting them dressed like this! What could they be planning for the Reveluvs?!

Perhaps we’ll be blessed with an updated version of “Be Natural” from their pre-debut days!

But this queen duo would definitely start a global domination should they decide to truly gear up together as a subunit!
