V posted a D-7 selfie, and he had in-ear monitors in his pocket.

Did you see the mirror selfie V posted on social media yesterday saying D-7?

The in-ear microphone was in the hoodie pocket
I could clearly see that they were getting ready for the rehearsal.

Even with his face half-covered, his signature playful pose
It felt like it conveyed the excitement exactly as it was.

It's really only a week now, from the album on the 20th to the Gwanghwamun concert on the 21st.
